What is cryptocurrency, how does it work – and what’s the point?
Cryptocurrency has been around for more than 15 years, and there is more than £1.8 trillion-worth of the stuff floating around on the internet.
Yet for all the tales of rows and riches that have engulfed crypto in recent years, not that many people can tell you what it actually is.
Even fewer can answer the simple question: what’s the point?
The PA news agency breaks it down.
– What is cryptocurrency?
Crypto is a type of digital money designed to be used over the internet. It does not exist physically, like dollars or pounds.
There are many types of crypto, but you have probably heard of the biggest and oldest one: Bitcoin.
Invented in 2008, a Bitcoin is essentially a computer file which is stored on an app, which functions as a digital wallet. There are many of these apps on the market.
You can send and receive crypto with other people – and it is frequently traded for money. Lots of it.
– How does it work?
Bitcoin is decentralised. That means it is not managed, recorded or stored by any one entity, like a national government or a bank.
Instead, every record is logged on a shared list called a blockchain.
Think of it like an online spreadsheet which no single person controls. Instead, it is shared around people who use it all over the world.
Those people get small financial rewards for keeping the ledger accurate and up-do-date. It is immutable, which means it is virtually impossible to go back and edit previous entries (or “blocks”).
This makes it attractive to people who want to break free of traditional currencies, and the influence that governments, central banks and financial institutions hold over them.
– What’s the point?
While there is a small, growing number of places that accept crypto as a real-world payment method, you’ll struggle if you try to use it to pay for most goods and services in the UK.
But the fact that you do not need to use a bank means that you can use crypto to operate outside the traditional financial system.
This appeals to people who want to send money across borders often, for example, where intermediaries often take a cut on transactions using traditional money.
It also makes it easier to act anonymously. Many crypto service providers do not have the same identity checks as banks.
As a result, it is generally harder to track where crypto has come from or where it is going than traditional currencies.
Unfortunately, that means criminal gangs or even terrorists often use it to launder money. Crypto is also sometimes used to transact illegally with sanctioned countries like Russia.
– Why do some people like it so much then?
Many people love crypto because it is extremely volatile, meaning you can make vast amounts of money very quickly by trading it at the right time.
One whole Bitcoin in October 2023 was worth about £27,000. Just a year later, that has nearly doubled.
Now consider if you had bought dozens of Bitcoins a decade ago, when they were valued at about £260, and you can see why some people are evangelical about it.
In that sense, it is different to investing in traditional assets, like stocks and shares, which are generally much more stable.
– Is it a safe investment?
No. Crypto has already been through several monumental boom-and-bust cycles already, which have done huge amounts of harm.
Millions of people put their life savings into cryptos like Bitcoin thinking it would make them better off.
But huge crashes in value in 2018 and 2022 left people’s finances in ruins – and the fact that it is still relatively unregulated means there have been a lot of scams.
The most high profile was in 2022, when FTX, the crypto exchange founded by Sam Bankman-Fried, collapsed.
Mr Bankman-Fried was later sentenced to 25 years in prison for defrauding customers out of billions of US dollars.
So while Bitcoin is near its record price again now, it is still generally considered extremely risky.
As the old adage goes: never invest more than you can afford to lose.

Report Shows Massive Increase in Iranian Bitcoin Adoption Amid Nationwide Unrest
A new report from blockchain analytics firm Chainalysis indicates there has been a massive increase in Bitcoin adoption in Iran over the past month, as the country deals with nationwide unrest and protests. The report specifically looks at the increase in withdrawals from crypto exchanges to unknown Bitcoin addresses, which indicates the local population is avoiding centralized financial infrastructure in the country in favor of the decentralized, peer-to-peer digital cash system.
In terms of specifics, the report shows a 262% increase in the amount of withdrawals valued at more than $10,000 into what are thought to be self-custodial bitcoin wallets since the nationwide protests began. According to the report, reasons for the increased interest in self-custodial bitcoin include the collapse in value in the Iranian rial and the potential increased need for citizens to operate outside of government-controlled financial channels.
The report also indicates spikes in Iranian crypto activity were seen during other major domestic and geopolitical events such as the Kerman bombings in January 2024, Iran’s missile strikes against Israel in October 2024, and the 12-day war. Nobitex, which is by far Iran’s largest and most popular exchange, was also hacked for $90 million during the 12-day war.
“This pattern of increased BTC withdrawals during times of heightened instability reflects a global trend we’ve observed in other regions experiencing war, economic turmoil, or government crackdowns,” says the report.
To Chainalysis’s point, this is not the first time a sharp increase in Bitcoin adoption has been noticed in a country dealing with some sort of crisis. In the past, Chainalysis has issued reports involving increased adoption in Ukraine amid war with Russia, Argentina and Venezuela’s respective currency devaluations, and more.
More recently, countries like Venezuela and Russia have used bitcoin and stablecoins like Tether’s USDT to avoid economic sanctions. According to another recent report from Chainalysis, this sort of sanctions avoidance was behind crypto’s record year of $154 billion worth of illicit financial use.
Unrest has persisted in Iran since late December, as protesters are fed up with the devaluation of the Iranian rial and other economic hardships. These grievances are compounded by longer-term issues such as corruption, repression, and general government mismanagement. In this way, the use of Bitcoin itself can also be seen as a form of protest where people are simply opting out of the traditional financial system.
Ironically, the Iranian regime has also been found to have used crypto for avoiding sanctions and laundering funds. In fact, the same Chainalysis report just released also indicates the Islamic Revolutionary Guard Corps (IRGC) accounts for roughly half of all crypto activity taking place in Iran, which is estimated at $7.78 billion. A recent report from TRM Labs also indicated two crypto exchanges in the United Kingdom were effectively fronts for the Iranian regime, and another past report from Elliptic shows Iran has been involved in bitcoin mining for purposes of monetizing their energy resources.
This situation illustrates the conundrum for authoritarian regimes around the world when it comes to Bitcoin, as the features that make it useful for the regime to avoid restrictions in the US-controlled global banking system also enable it to be used for the local population to gain greater financial freedom.
Bitcoin is not the only technology that has proven helpful for Iranians during the protests, as the existence of Starlink is one of the only reasons information has been able to get out of the country amid government-imposed internet blackouts. While mesh-networking based Bitchat has seen increased adoption in other countries dealing with turmoil recently, a forked version of the app called Noghteha has gained notoriety in Iran. Although, there has been controversy with Noghteha due to its closed source aspects and collection of donations.
