Should you decide to invest in cryptocurrency or in any other investment, you should always obtain appropriate financial advice and only invest what you can afford to lose.

From Bitcoin and Ethereum to Dogecoin and Tether, there are thousands of different cryptocurrencies, potentially making it overwhelming when investors are first considering getting started in the world of crypto.  

These are our pick of some of the top cryptocurrencies based on their market capitalisation – the total value of all the coins currently in circulation.

What are cryptocurrencies?

A cryptocurrency is a high-risk digital asset that can circulate without the centralised authority of a bank or government.  

To date, there are over 26,000 cryptocurrency projects out there that represent the entire £917 billion crypto market.

1. Bitcoin (BTC)

  • Market cap: £553 billion

Created in 2009 by Satoshi Nakamoto, Bitcoin (BTC) is the original cryptocurrency. As with most cryptocurrencies, BTC runs on a blockchain, or a ledger logging transactions distributed across a network of thousands of computers. Because additions to the distributed ledgers must be verified by solving a cryptographic puzzle, a process called proof of work, Bitcoin is intended to be kept secure and safe from fraudsters.

Bitcoin’s price has both skyrocketed and plummeted over its lifetime. In May 2016, the price of a single Bitcoin was worth about £370. As of 7 November 2023, the figure is around £28,000.

2. Ethereum (ETH)

  • Market cap: £184 billion

Both a cryptocurrency and a blockchain platform, Ethereum is a favourite of some programme developers because of its potential applications, like so-called smart contracts that automatically execute when conditions are met and non-fungible tokens (NFTs).

Ethereum’s price has also experienced tremendous highs and lows. From April 2016 to the 7 November 2023, its price went from about £8 to around £1,530.

3. Tether (USDT)

  • Market cap: £69 billion

Unlike some other forms of cryptocurrency, Tether (USDT) is a stablecoin, meaning it’s pegged to fiat currencies like US dollars and the Euro and hypothetically keeps a value equal to one of those denominations. In theory, this means Tether’s value is supposed to be more consistent than other cryptocurrencies, and it’s preferred by some investors who are wary of the extreme volatility of other coins.

4. Binance Coin (BNB)

  • Market cap: £30 billion

Binance Coin can be used for trading, payment processing or even booking travel arrangements. It can also be traded or exchanged for other forms of cryptocurrency, such as Ethereum or Bitcoin.

In 2017 it was priced under 10p. By 7 November 2023, its price had risen to around £203. As with other cryptocurrencies, the ride along the way has been highly volatile.

5. Ripple (XRP)

  • Market cap: £29 billion

Created by some of the same founders as Ripple, a digital technology and payment processing company, XRP can be used on that network to facilitate exchanges of different currency types, including fiat currencies and other major cryptocurrencies.

At the beginning of 2017, the price of XRP was £0.004. As of 7 November 2023, its price reached £0.55.

6. US Dollar Coin (USDC)

  • Market cap: £19 billion

Like Tether, USD Coin (USDC) is a stablecoin, meaning it’s theoretically pegged to the currency of the US dollar and aims for a 1 USD to 1 USDC ratio. USDC is powered by Ethereum, and can be used to complete global transactions.

7. Solana (SOL)

  • Market cap: £14 billion

Developed to help power decentralised finance (DeFi) uses, decentralised apps (DApps) and smart contracts, Solana runs on a unique hybrid proof-of-stake and proof-of-history mechanisms aimed to process transactions quickly and securely. SOL, Solana’s native token, powers the platform.

When it launched in 2020, SOL’s price started at £0.57. By November 2023, its price was around £33.34.

8. Cardano (ADA)

  • Market cap: £10 billion

Somewhat later to the crypto scene, Cardano (ADA) is notable for its early embrace of proof-of-stake validation. This method is designed to expedite transaction time and decrease energy usage and environmental impact by removing the competitive, problem-solving aspect of transaction verification in platforms like Bitcoin. Cardano also works like Ethereum to enable smart contracts and decentralised applications, which ADA, its native coin, powers.

In 2017, Cardano’s ADA token’s price was about £0.015. As of 7 November 2023, its price was at £0.28.

9. Dogecoin (DOGE)

Market cap: £8.5 billion

Dogecoin was famously started as a joke in 2013 but rapidly evolved into a prominent cryptocurrency thanks to a dedicated community and creative memes. Unlike many other cryptos, there is no limit on the number of Dogecoins that can be created, which leaves the currency susceptible to devaluation as supply increases.

Dogecoin’s price in 2017 was £0.00016. By November 2023, its price was at £0.06.

10. TRON (TRX)

  • Market cap: £6.9 billion

Much like Solana, TRON is a blockchain designed to run smart contracts and other DeFi applications. TRX is the platform’s native cryptocurrency, which powers its proof-of-stake consensus algorithm.

TRON was founded in 2017, and TRX was initially valued at 0.015p per token. TRX is currently valued around £0.07.

Cryptocurrency is unregulated in the UK. The UK regulator, the Financial Conduct Authority, has repeatedly warned investors that they risk losing all their money if they buy cryptocurrency, with no possibility of compensation.

Frequently Asked Questions (FAQs)

What are cryptocurrencies?

Cryptocurrency is a form of currency that exists solely in digital form, and is a high risk investment. Cryptocurrency can be used to pay for some purchases online without going through an intermediary, such as a bank, or it can be held as an investment.

How does trading cryptocurrencies differ from stocks?

While it’s possible to invest in cryptocurrencies, they differ a great deal from traditional investments, such as stocks and shares.

When an investor buys stock, they are buying a share of ownership of a company, which means they’re entitled to do things like vote on the direction of the company. If that company goes bankrupt, they may also receive some payment once its creditors have been paid from its liquidated assets.

Buying cryptocurrency doesn’t grant investors ownership over anything except the token itself; it’s more like exchanging one form of currency for another. If the crypto loses its value, the cryptocurrency’s owner suffers accordingly from the price drop.

There are several other key differences to keep in mind:

  1. Trading hours: Stocks are only traded during stock exchange hours. For example, trading hours for the London Stock Exchange run from 8:00am till 4:30pm, Monday to Friday. Cryptocurrency markets never close, so trading takes place 24 hours a day, seven days a week
  2. Regulation: Share trading is subject to regulation and the finances of listed companies are matters of public record. By contrast, cryptocurrencies are not regulated investment vehicles, so investors may not be aware of the inner dynamics of their crypto or the developers working on it
  3. Volatility: Investing in both stocks and cryptocurrency involve risk with the potential for both to lose, as well as make, money. However, stocks are directly linked to companies and generally rise and fall based on those companies’ performance. Cryptocurrency prices are more speculative – no one is quite sure of their value yet. That makes them much more volatile and affected by something as small as a celebrity tweet.

Is there tax to pay on cryptocurrency?

It’s important to pay attention to tax rules as they potentially apply to cryptocurrency.

Cryptocurrency is treated as a capital asset, like stocks, rather than cash. That means if cryptocurrency is sold at a profit, the profits are subject to capital gains taxes.

This is the case even if crypto is used to pay for a purchase. If investors receive a greater value for it than they paid, then they’ll owe taxes on the difference, subject to the usual tax allowances.

Tax treatment depends on one’s individual circumstances and may be subject to changes in the futue.

Are there cryptocurrency Exchange-Traded Funds (ETFs)?

Given the thousands of cryptocurrencies in existence (and the high volatility associated with most of them), investors have the option of taking a diversified approach to investing in crypto to potentially minimise the risk of losing money.

Cryptocurrency ETFs started to make an appearance at the end of 2021.
