YOU won’t find cryptocurrencies like Bitcoin or Dogecoin hanging around in your loose change.
Cryptocurrencies have to be “mined” in order to be created, which is a complex and painstaking process involving a lot of computer power.

Miners create new cryptocurrencies using a complex computer code.
These new coins are then stored virtually through an online database called the blockchain.
Before investing in any cryptocurrency, you should be aware of all the risks involved.
Their value is highly volatile – so while coins may rocket in value one day, they could tumble in the blink of an eye.
City watchdog the Financial Conduct Authority has warned investors should be prepared to lose all their money.
Investing in cryptocurrencies is not a guaranteed way to make money – and as always, you should never invest in something you don’t understand.
Here’s what you need to know about how coins are created:
What is cryptocurrency?
Cryptocurrencies are digital currencies which are stored on an online network called the blockchain.
Blockchain technology, which can seem very complicated, is a kind of database used to record financial transactions.
Bitcoin is thought to be the first cryptocurrency that was invented.
It was created in 2009 by a mysterious online account which went by the name Satoshi Nakamoto.
Mr Nakamoto devised a complicated set of computer codes and maths problems that could be solved using computer processors to generate Bitcoins.
Individual Bitcoins are created by computer code.
You can collect coins by solving computer equations – which is a process called mining.
The majority of other cryptocurrencies are created using a similar mining process, including Dogecoin.
Dogecoin, which has the image of a Shiba Inu dog as its logo, was originally created as a joke by software engineers Jackson Palmer and Billy Markus.
But it has since boomed in value and has been backed by celebrities such as Elon Musk.
What is mining and how does it work?
Mining cryptocurrencies is a complex and energy-intensive process, which requires a lot of computer power.
Bitcoin is one of the most popular cryptocurrencies, and the process for mining it is similar for other coins, including Dogecoin.
Mining Bitcoin involves using a computer to solve a mathematical problem with a 64-digit solution.
For each problem solved, one block of Bitcoin is processed. In addition, the miner that is first to solve the problem is rewarded with new Bitcoin.
To compensate for the growing power of computer chips, the difficulty of the puzzles is adjusted to ensure a steady stream of new Bitcoins are produced each day.
There are only about 21million Bitcoins that can be mined, and roughly 18.5 million have been found so far.
To receive a Bitcoin, a user must have a Bitcoin address – a string of 27-34 letters and numbers – which acts as a kind of virtual postbox.
These addresses are in turn stored in Bitcoin wallets, which are used to manage savings.
The bulk of Bitcoin “mining” is done in China, where energy costs are cheaper than in places like the UK or US.
Is it safe to invest in cryptocurrencies?
Anyone thinking of investing in cryptocurrencies should be very careful.
Their values are incredibly unpredictable, with the ability to plummet as quickly as they shoot up.
For instance, the price of Bitcoin has jumped more than 4% this morning to $34,264.67 following news that El Salvador has become the first country to approve it as a legal tender.
But it is down sharply compared to its record-breaking high of $64,536 in April, essentially halving in value within two months.
The crash followed a shock announcement by Elon Musk, who revealed Tesla would no longer accept Bitcoin due to “concerns” about the impact the cryptocurrency has on the environment.
The tumble was fuelled further by the announcement that China has banned banks from providing services related to cryptocurrency transactions.
It also warned investors against speculative crypto trading.
Dogecoin has also experienced wild swings in value.
The cryptocurrency peaked at $0.7166 ahead of Elon Musk’s appearance on SNL.
But it’s dipped in value since then, and at the time of writing, stands at $0.3249.
You can be left with less money than you put in and remember, you should never invest money that you can’t afford to lose.
Investors have also been warned to avoid new cryptocurrencies PooCoin and SafeMoon or risk losing their money.
Both of the coins are new and launched last month on March 8 – but little is know about them and whether they are legitimate.
The latest bizarre launch, PooCoin, has a logo shaped like the poo emoticon, which may appear to be a joke.
SafeMoon technically isn’t a cryptocurrency but a decentralised finance (DeFi) token, according to its website.
