Cryptocurrency
The basics, the advantages and the risks.
What is cryptocurrency?

Cryptocurrencies like Bitcoin and Ethereum are digital assets recorded on blockchains.
There are no coins or notes to hold. A cryptocurrency exists only in digital form.
The money we use every day is issued and overseen by central banks. Cryptocurrencies are developed and run by groups, individuals or companies.
A blockchain is a digital ledger kept in a distributed fashion, usually with no central authority such as a bank, company or government.
The US CFTC says virtual currency does not have legal tender status, and that virtual currencies are not currently backed nor supported by any government or central bank.
How does cryptocurrency work?
A shared record
Transfers are recorded in blocks. Copies of the ledger are kept across a network of computers.
Hard to change
As new blocks are added, older blocks become more difficult to change.
Keys and wallets
You sign a transfer with a secret code called a private key. People keep their keys in digital wallets. If a private key is lost, the crypto linked to it is lost too.
Trading platforms
Much of the crypto market runs on internet trading platforms that may be unregulated and unsupervised.

What do the key words mean?
- Bitcoin
- The longest-running cryptocurrency, created in 2009.
- Ethereum
- A blockchain that can run smart contracts: computer code that acts by itself when agreed conditions are met.
- Stablecoin
- A crypto whose value is meant to be linked to a stable asset, such as the US dollar or gold. Some have lost that link, and their value.
- Public blockchain
- A blockchain that needs no permission to join. On public blockchains, like the one Bitcoin uses, all information is publicly available. Crypto is not always private.
- Volatility
- How much and how fast a price moves up and down.
What moves crypto prices?
Cryptocurrencies are among the most volatile assets you can trade.
The US CFTC says the value of virtual currencies is completely derived by market forces of supply and demand.
Some cryptos, called unbacked, have nothing you can see or touch behind them, such as gold or cash.
Their price can rise or fall depending on whether other people are willing to buy them. If people stop buying, the price could fall dramatically.
What are the advantages?
Crypto markets trade around the clock, seven days a week.
The UK FCA says the technology behind crypto might lower costs and speed up payments in the future.

What are the risks?
Virtual assets may lose their value in part or in full, and are subject to extreme volatility at times. You can lose all the money you invest, and you do not benefit from any form of financial protection.
ETTFOS has a commercial interest here: it sells trading education, and its course contents include cryptocurrencies.
If you decide to invest in crypto then you should be prepared to lose all your money, for reasons including sudden market moves, the failure of a firm, poor segregation of client funds or cyberattacks.

On data from August 2015 to December 2022, a majority of crypto app users in nearly all economies made losses on their bitcoin holdings.
