Quantum Cryptocurrency – Securing The Future Of Digital Assets

Cryptocurrency, like Bitcoin, is digital money you can send or receive without banks, and it’s stored securely online. In 2025, Bitcoin hit a record $111,880, making up 56.7% of the $3.88 trillion crypto market. But new, super-powerful computers called quantum computers could one day hack regular cryptocurrencies. That’s where quantum cryptocurrency comes in. It’s a new type of crypto designed to stay safe even if quantum computers arrive.

Let’s explores quantum cryptocurrency, its real-world implementations, and how it safeguards the future of crypto.

What is Quantum Cryptocurrency?

Quantum cryptocurrency refers to digital currencies and blockchains using quantum-resistant cryptographic algorithms to protect against quantum computing attacks. To keep it simple, it is digital money built to be extra secure against quantum computers. Regular cryptocurrencies, like Bitcoin, use math puzzles to keep your money safe. These puzzles are hard for normal computers to crack, but quantum computers, superfast machines that work differently, might solve them someday, putting your money at risk.

Quantum cryptocurrency uses new, stronger math puzzles that even quantum computers can’t break. Think of it like a lock that’s impossible to pick, no matter how advanced the thief’s tools are. It’s still digital money you can use to buy things, trade, or save, but it’s designed to stay safe in the future. Here’s a short video by Algorand which explains how Quantum Computing attacks:

Quantum computers are still rare and not strong enough to hack crypto yet, but companies like Google and IBM are making them better every year. Google’s new Willow chip, for example, can do some calculations in minutes that would take regular computers billions of years. If quantum computers get powerful enough, they could steal Bitcoin or other crypto by cracking their security codes. Quantum cryptocurrency protects your money by using new security methods that quantum computers can’t break. By switching to quantum-safe crypto, you can keep your money secure even as technology changes.

Quantum Cryptocurrency Projects

Several companies and projects are working on quantum cryptocurrency to make crypto safer. Here are the main ones as of 2025:

1. Quantum Resistant Ledger (QRL)

 

  • What They Do – QRL is a cryptocurrency, like Bitcoin, but built to be safe from quantum computers. It uses a special lock called XMSS that’s super hard to crack. You can buy QRL on exchanges like Coinbase and use it to send money or run apps

  • QRL is one of the first coins designed specifically for quantum safety, making it a leader in this space.

2. Algorand (ALGO)

Quantum Cryptocurrency

  • What They Do – Algorand uses Falcon, a post-quantum digital signature, to sign its blockchain history every 256 blocks, securing past transactions. While not fully quantum-resistant, its roadmap includes PQC upgrades.

  • Algorand balances scalability and quantum security for DeFi applications. Algorand is used for fast, cheap transactions and apps, and its quantum focus makes it a trusted name for investors. 

3. Nervos Network (CKB)

Quantum Cryptocurrency

  • What They Do –  Nervos runs a blockchain called CKB (Common Knowledge Base) that supports apps and digital money. It’s starting to use quantum-safe security to protect users’ funds. Nervos’ CKByte (CKB) operates on a dual-layer PoW blockchain, combining security and scalability. Its quantum-resistant features leverage NIST’s PQC standards, making it a versatile platform for dApps and asset storage.

  • Nervos makes it easy for developers to build secure apps, which could bring more people to quantum-safe crypto.

4. QuChain AI ($QC)

  • What They Do – Launched on Uniswap in May 2025, QuChain AI’s $QC token powers an AI-driven, quantum-secure blockchain using PQC encryption. It combines artificial intelligence (AI) with quantum-safe security to create a blockchain for smart apps

  • QuChain’s mix of AI and quantum safety could make crypto easier and safer to use.

5. Big Tech and Governments

  • Companies like Google and IBM are building quantum computers, while the U.S. government’s NIST group created new security standards in 2024 to fight quantum hacks. These standards help projects like QRL and Algorand stay safe. Big tech and governments are pushing quantum tech forward, making quantum-safe crypto more urgent.

How to Invest in Quantum Cryptocurrency

To engage with quantum cryptocurrency:

  • Choose Quantum-Resistant Coins: Invest in QRL (~0.38), Algorand, or Nervos (CKB) via exchanges like Coinbase or Binance. Check fees, they’ll typically be under 1%.

  • Secure Wallets: Use hardware wallets supporting PQC signatures, like QRL’s wallet, and enable 2FA. Never share private keys!

  • Report Scams: Fraudulent quantum crypto projects are rising. Report suspicious activity to ic3.gov or local regulators.

The Future of Quantum Cryptocurrency

In 2025, quantum cryptocurrency is growing fast. More projects are adopting quantum-safe security, and big names like Ethereum are planning upgrades. People on social media are buzzing about tokens like $QC, but they also warn about fakes. By 2030, quantum computers might be stronger, so coins like QRL and Algorand could become more popular to keep your money safe.

FAQ: Understanding Key Terms

  • Quantum Computers: Super-powerful computers that use special science (quantum physics) to solve problems much faster than regular computers. They could one day hack regular crypto, but they’re not strong enough yet.

  • Post-Quantum Cryptography (PQC): A new type of security that uses math puzzles so tough that even quantum computers can’t crack them. It’s like an unbreakable lock for your crypto.

  • NIST: The National Institute of Standards and Technology, a U.S. government group that sets rules for secure technology. In 2024, NIST created new PQC standards to keep crypto safe from quantum hacks.

  • XMSS: A special security lock (called eXtended Merkle Signature Scheme) used by QRL to protect your money from quantum computers. It’s like a super-strong password.

  • Falcon: Another security lock (a type of digital signature) used by Algorand to keep its blockchain safe. It’s designed to stop quantum hacks.

  • Digital Wallet: A phone app or device (like a USB) that stores your crypto securely, like a digital piggy bank. You need a private key (a secret code) to open it. Never share this private key with anyone.

  • Two-Factor Authentication (2FA): A security step where you use combinations of two things. So a combination of a password and a code sent to your phone to prove it’s you when accessing your account.

Best Ways to Buy Cryptocurrency in Australia (2026) | Platforms, Payment Methods & Tips

The Australian government is in the midst of tightening regulations on the crypto industry, which could increase consumer protections while strengthening crypto’s reputation as a financial asset.

In September, the government released draft legislation that would require more digital asset platforms and tokenized custody platforms to obtain an Australian Financial Services License and register with the Australian Securities and Investments Commission (ASIC).

These changes also highlight the difference between custodial platforms that hold assets on your behalf and non‑custodial wallets like Best Wallet, where you control your own keys regardless of which Australian exchange you use to buy crypto.

This differs from current Australian law, which doesn’t inherently include crypto as a financial product with registration requirements. Instead, crypto might be regulated by ASIC if it meets the standard for being a financial product, such as if an initial coin offering (ICO) is used, which includes rights to a share of another company that the ICO funds.

Any new legislation would likely raise the compliance bar, though there may be exceptions for small platforms. While additional regulations may make things a little more cumbersome for some platforms, it could also bring more trust and transparency to the Australian crypto industry.

Crypto also faces some regulations that fall under broader rules, like anti-money laundering/combating the financing of terrorism (AML/CMT) requirements. If a business exchanges fiat currency for digital currency or vice versa, it would generally be considered a digital currency exchange and have to register with the Australian Transaction Reports and Analysis Centre (AUSTRAC), which oversees compliance for areas like AML/CMT. Once you have purchased crypto through an AUSTRAC‑registered exchange, you can transfer it to a non‑custodial wallet such as Best Wallet to store and manage your assets outside of an exchange account.

Basics of buying crypto in Australia

Crypto assets in Australia are considered property for tax purposes, as regulated by the Australian Tax Office (ATO). Generally, trades can trigger capital gains taxes, just like for other securities such as stocks.

Amidst this compliance backdrop, it’s important for individuals to understand that buying bitcoin or other crypto in Australia does come with some guardrails similar to other types of investing. But at this point, the regulations aren’t as fleshed out as they are for more traditional financial markets.

Still, it can be useful to plan ahead for things like capital gains taxes and ensure that a platform you use to buy or sell crypto is registered with the proper authorities if required. You might also prefer to wait to trade until legislation is finalized to buy or sell crypto in Australia. Others might be more comfortable transacting on more of a peer-to-peer basis, without regulatory involvement. Keep in mind that this direct approach can come at the expense of some consumer protections.

Best ways to buy crypto in Australia

To buy bitcoin or other types of crypto in Australia, consider using the following types of platforms:

Centralized Crypto Exchanges (CEXs)

Centralized crypto exchanges (CEXs) typically resemble stock exchanges from the buyer’s point of view, and they’re generally on the more regulated side of crypto — though still perhaps not as much as stock exchanges. In general, CEXs have to register with AUSTRAC as digital currency exchanges, meaning they have to follow verification procedures, like Know Your Customer (KYC) requirements.

While it can reduce privacy, some buyers prefer KYC requirements because it can help them feel more confident that they’re transacting with trustworthy parties. Still, CEXs tend to have benefits like strong liquidity and ease of use, especially for beginners, because CEXs often custody assets on your behalf. Some investors may prefer to self-custody their assets, where you maintain your own private keys to your wallet. Much depends on your comfort level and trust.

Within Australia, some popular homegrown CEXs include Swyftx, CoinSpot, CoinJar, and Independent Reserve. International CEXs like Gate, Coinbase, Binance, and Kraken also operate in Australia.

Decentralized Crypto Exchanges (DEXs)

For crypto traders who want more privacy, decentralized crypto exchanges (DEXs) might be preferred. Unlike CEXs, you generally don’t need an ID to create an account and don’t have to go through KYC requirements. Some popular global DEXs that can be used by buyers in Australia include PancakeSwap, SushiSwap, and UniSwap.

These platforms generally aren’t regulated in Australia because they typically don’t meet the threshold to be considered a digital currency exchange. Instead of the DEX holding assets and exchanging crypto for other currencies, you generally connect your wallet to the DEX to trade with other parties through the platform. The DEX isn’t actually taking possession of the crypto.

That can come with some potential downsides, like making it harder to verify the legitimacy of the other trading partner on the platform. You might be more comfortable with a platform that uses smart contracts that essentially put assets in escrow on a blockchain and release them only if the transaction is properly completed.

Still, there can be other downsides to DEXs vs. CEXs, such as lower liquidity and slippage, meaning prices end up being more expensive than you expected when trying to buy the crypto.

Peer-to-Peer (P2P) crypto platforms

DEXs often resemble P2P platforms, and in some cases, the terms might even be used interchangeably. However, P2P platforms may go beyond connecting buyers and sellers via smart contracts by holding assets on behalf of the parties and allowing for the exchange of fiat to crypto, which could mean having to register with AUSTRAC in Australia.

There are many informal P2P platforms outside of the remit of AUSTRAC, which arguably creates risks, such as more potential for money laundering.

Some examples of P2P platforms available in Australia include LocalCoinSwap and Paxful. Binance, which is largely a CEX, also has a P2P platform.

Crypto ATMs in Australia

Another way to buy crypto in Australia is through certain digital currency ATMs. Similar to traditional ATMs, many of these machines enable you to deposit or withdraw cash, but the difference is that you generally connect your crypto wallet to facilitate an exchange of cash to crypto or vice versa.

If this fiat-to-digital exchange happens, the ATM is supposed to register with AUSTRAC, so there may be identity verification requirements for users. While some investors may prefer more privacy, using an unregulated ATM carries risks such as opening your wallet up to unscrupulous parties, or unwittingly facilitating money laundering. Even regulated ATMs pose risks, as they are often used in connection with scams, because once you convert cash to crypto through these ATMs, the transaction is almost impossible to unwind.

The convenience of ATMs for quick transactions is a draw for some investors, though you should still think twice about why you’re using that ATM and if the company seems trustworthy. Some examples of regulated crypto ATM companies available in Australia include ByteFederal, Cryptolink, and Localcoin.

Australian brokerages and mobile apps

Another way to buy crypto in Australia is through financial brokerages and mobile apps that often offer access to a wide range of assets, such as stocks, options, and exchange-traded funds.

The advantage of using a brokerage is that you can hold all of your investments within one platform, including crypto. These are also generally regulated platforms similar to CEXs, and they custody assets for you. This can be appealing to investors looking for ease of use and compliance controls, while others might prefer more privacy. Some brokerages and apps charge high fees for crypto transactions, so always review fee schedules carefully.

A few examples of these platforms that offer crypto trading alongside other assets include eToro, Revolut, and CMC Markets.

Buy and manage crypto with Best Wallet

If you want a private, multi-chain, no-KYC way to buy and manage crypto — without using a CEX, DEX, ATM, or legacy app — consider Best Wallet. It’s a mobile-first, non-custodial wallet that provides an all-in-one solution, where you can track trending coins, buy/swap 60+ cryptos, discover vetted presales, and use advanced safety features.

Step 1: Download and set up Best Wallet

Download the Best Wallet app from the Australian Apple App Store or Google Play and create an account with your email address.​

Set a secure PIN and enable biometric login if your device supports it, so only you can access the wallet.​

Step 2: Go to the Buy section

Open the app and tap the Buy or Trade section in the main dashboard.​

Choose the cryptocurrency you want to purchase, such as bitcoin, ethereum, or another supported coin.​

Step 3: Enter how much you want to buy

Enter the amount you want to invest in Australian dollars (AUD); the app shows how much crypto this will buy at current prices, including estimated fees.​

You can usually start with relatively small amounts, which is useful if you are new to buying crypto through a wallet app.​

Step 4: Choose a payment method and provider

Select a supported payment method through Best Wallet’s integrated providers, such as debit or credit card and other on‑ramp options available for Australian users.​

Compare the quoted fees and exchange rate, then confirm the purchase once you are comfortable with the total cost.​

Step 5: Store and manage your crypto

After the transaction is processed, your coins are delivered straight into your non‑custodial Best Wallet, so you hold the private keys instead of leaving funds on an exchange.​

From there, you can hold, swap, or send crypto, and, if you want additional cold‑storage security, move some holdings to a hardware wallet later on.​

Best payment methods to buy crypto in Australia

To some extent, the payment method you can use to buy crypto in Australia depends on where you buy crypto. Some of the most popular ways to buy crypto — which might also influence which platform you transact through, given available payment methods — include the following:

  • Bank transfer: Through some platforms, such as many CEXs and brokerage apps, you can deposit money via bank transfer, such as through Australia’s PayID system. That makes it easy to convert fiat currency into crypto. You just complete the bank transfer, choose the crypto you want to buy, and complete the swap from Australian dollars into your chosen crypto.
  • Debit/credit cards: Some platforms — typically more regulated ones like CEXs and brokerage apps — also allow you to deposit money via debit or credit cards. This works similarly to bank transfers but often even faster, though there may be additional fees. It also comes with privacy tradeoffs, and you want to be careful about getting into credit card debt to buy crypto.
  • BPAY: BPAY is also similar to bank transfers, though it’s a third-party company that facilitates bill payments from an Australian bank. It can be used to buy crypto through many exchanges and allows recurring deposits.
  • Cash in person: With some P2P deals, you can meet up in person and exchange cash for crypto. This often works by the crypto being placed into escrow, which the seller then releases once you give them the cash. This can make for more private transactions, but it increases the risk of dealing with unscrupulous parties.
  • Prepaid debit cards or vouchers: Similar to cash transactions, you could potentially use prepaid debit cards or vouchers on some platforms, with those funds then converted into crypto. Doing so can help maximize anonymity, but also can be risky, such as if you don’t receive the crypto you were promised via a P2P transaction — in that case, it can be extremely difficult to unwind the funds back to you.
  • Crypto swaps: If you already own crypto, you can often swap that for other coins or tokens on various platforms, particularly DEXs or P2Ps. This can help maintain privacy and avoid the step of converting fiat currency into crypto, but pay attention to issues like conversion rates.

Tips for first-time Australian crypto buyers

If you’re new to buying crypto in Australia, consider the following tips, which can vary based on your preferences:

  • Do your own research: The crypto world offers a lot of exciting possibilities, but it’s also full of people trying to pump random coins or conduct outright scams. Don’t take anything at face value. Do your own research first.
  • Start conservatively: Because crypto can be riskier and more complex than some traditional assets, avoid investing significant amounts of money that you can’t afford to lose. There’s no shame in starting with a small investment until you get more comfortable with buying and selling crypto.
  • Consider privacy/anonymity tools: If you’re concerned about privacy or if you’re supporting a cause that you don’t want others to know about, you might try to preserve your anonymity as much as possible. You can do this by buying privacy coins when possible to then conduct more transactions, as well as using anonymous wallets and browsing tools. You might initially fund these via a privacy-focused method like a prepaid debit card rather than linking your personal bank account.
  • Remember taxes: Don’t overlook the tax implications of crypto investments. If you have capital gains from the sale of an asset, you generally will owe taxes, so it’s better to plan ahead than get caught off guard with a big tax bill.
  • Store crypto securely: Make sure you’re following best practices to keep your crypto safe, such as never giving anyone the private key to your wallet and using two-factor authentication if you have an account on an exchange or brokerage app. Consider using a non-custodial wallet to ensure you control your private keys and who can access your assets.

Frequently Asked Questions (FAQ) about buying crypto in Australia

Is buying crypto legal in Australia?

Yes, buying crypto is legal in Australia. The government is currently in the midst of expanding regulations for crypto to treat these assets more as financial products. Many Australians also use non‑custodial wallets such as Best Wallet to hold coins they’ve bought on AUSTRAC‑registered exchanges, combining regulated on‑ramps with self‑custody.

What’s the safest exchange in Australia?

The safest exchange in Australia depends on your preferences, such as whether you value privacy or the solvency of a crypto exchange. Consider factors such as an exchange’s track record, privacy controls, and security practices if the platform is custodying your assets.

Can I buy crypto without ID in Australia?

Yes, you can often buy crypto without ID in Australia, for example, by using DEXs or P2P platforms. Keep in mind that while not using an ID may grant you more privacy, it can then make it harder to recover assets, such as if you get caught up in a crypto scam. You can often browse and set up a non‑custodial wallet app like Best Wallet without full ID checks, but regulated Australian on‑ramps still have to verify you when you convert between AUD and crypto.

What’s the best wallet for crypto in Australia?

The best wallet for most Australians is a non-custodial, multi-chain wallet, like Best Wallet. It lets you securely buy, store, and swap dozens of cryptos, track trends, and manage presales directly in-app. With advanced safety features (scam scanner, contract checks, biometric login) and no KYC required, Best Wallet helps users stay in control of their assets. Always use a wallet where you hold your own private keys.

Are crypto presales safe for Australians?

Crypto presales can offer early access to new projects, but they are high-risk and can be targeted by scams. Australians should always use wallets with contract safety checkers and scam filters, verify a project’s legitimacy, and confirm all official presale links. Only invest what you can afford to lose, and understand any local regulations around early-stage token access.

Is the US dollar the world’s most successful cryptocurrency?

Is the US dollar the world’s most successful cryptocurrency?

The U.S. dollar, to be clear, is not a cryptocurrency. But for many people, it is doing the job that cryptocurrencies like Bitcoin were originally intended to fill. To understand what is going on, and why the implications are so important for the global economy, it is worth going back to some of the original visions of Bitcoin.

Bitcoin got its start, back in 2008, during the dark days of the global financial crisis. At that time, the U.S. government, among many others, was bailing out banks and financial companies and “printing money” to strengthen the economy. While central banks like the Federal Reserve were not, literally, printing money and throwing it out of helicopters to people, they were doing some quite extraordinary things in the name of “quantitative easing.”

The idea behind quantitative easing (or “helicopter money”) was that central banks could inject confidence into the economy by, in effect, promising to buy just about any kind of financial asset if you had trouble selling it. And at that moment, the catalog of unsaleable assets ran to hundreds of billions of dollars.

With the benefit of hindsight, this looks like a good decision when the alternative was a repeat of the Great Depression. At the time, it looked both unfair and risky to many bystanders. Unfair because taxpayer money was being used to buy assets from people who probably deserved to go bankrupt in normal circumstances. And risky because printing so much money, in normal times, is recipe for higher inflation.

Bitcoin was deliberately designed, from the ground up, to make both of these options impossible. The strict release schedule for Bitcoin and the absolute limit of 21 million Bitcoins being issued meant that there was no way to “bail out” bad lenders or debase the value of the currency by issuing too much. The Bitcoin white paper specifically talks about resistance to corruption, and the Bitcoin network itself contains a reference to bank bailouts in the genesis block.

In the end, there was no hyperinflation in the major economies that practiced some form of quantitative easing, such as the U.S., U.K., and EU. However, hundreds of millions of people do live in countries with high inflation rates, and in the case of a few countries, are facing actual hyperinflation. For those people, Bitcoin should be especially appealing.

So it is all the more surprising to find that, 15 years since the end of the Great Recession, it is the U.S. dollar, not Bitcoin, that is the preferred choice of millions of people in emerging markets.

The appeal, for many of these people, is that to them, the U.S. dollar looks like an ideal stable, corruption-free digital asset. It’s extremely well known. It’s backed by the full faith and credit of the U.S. government, and people have been using the dollar as a “safe haven” in periods of risk for decades.

American power, the huge range of American brands, and the vast reach of American culture have made the U.S. dollar the best-known currency in the entire world. When someone says, “the buck stops here” or refers to the “greenback,” we all know what they’re talking about. And, if you live far from the U.S. and don’t pay much attention to U.S. politics, then compared to your own currency, the U.S. dollar may well look very safe indeed.

Most of this situation has, in fact, been generally the case for decades. There are billions of U.S. dollars circulating around the world in cash, but for most people, that’s not a very safe or secure option. What has changed recently, however, is the ability of just about anyone anywhere to get access and hold dollars digitally.

Cryptocurrencies made it possible for anyone to have digital assets in a private, personal wallet, but few people had the technical knowledge or access to make this possible early on. More recently, cheap smartphones, better wallet software and, most importantly, stablecoins have recently made it possible for anyone, anywhere, to have what is, for all practical purposes, a U.S. dollar-denominated bank account. They see it as a safer alternative to their own currency, something easier to understand than crypto, and very preferable to carrying around U.S. dollars in cash.

And for many of those people, they don’t even realize they are using cryptocurrency infrastructure. Opera Mini Pay is one of the world’s most popular digital wallets and is a good example of what’s ahead. People all around the world can buy, sell and transact in U.S. dollars. And even though Opera Mini Pay runs on top of the Ethereum Layer 2 network CELO, all the fees and other services can be paid in U.S. dollars. No need to know anything at all about crypto.

The result is that even as crypto has laid down the path, when it comes to currencies, the overwhelming brand of the almighty U.S. dollar has ended up filling the gap Bitcoin brought to everyone’s attention.
