Top 10 Cryptocurrencies In March 2023 – Forbes Advisor UK

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

To help you get your bearings, these are the top 10 cryptocurrencies based on their market capitalisation – the total value of all the coins currently in circulation.

What Are Cryptocurrencies?

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

To date, there are 23,171 cryptocurrency projects out there that represent the entire £954 billion crypto market.

The UK financial regulator, the Financial Conduct Authority, has issued repeated warnings about the risks faced by those who invest in cryptocurrency, stating that all funds are at risk and investors could lose everything. Cryptocurrency trading is largely unregulated in the UK and no compensation arrangements are in place.

1. Bitcoin (BTC)

• Market cap: £438.8 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 kept secure and safe from fraudsters.

Bitcoin’s price has skyrocketed as it’s become a household name. In May 2016, you could buy one Bitcoin for about £370. As of 4 April 2023, a single Bitcoin’s price was around £22,694. That’s a growth of 6,034%.

2. Ethereum (ETH)

• Market cap: £179.7 billion

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

Ethereum has also experienced tremendous growth. From April 2016 to the beginning of April 2023, its price went from about £8 to around £1,492, increasing approximately 18,545%.

3. Tether (USDT)

Unlike some other forms of cryptocurrency, Tether (USDT) is a stablecoin, meaning it’s backed by fiat currencies like U.S. 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 favoured by investors who are wary of the extreme volatility of other coins.

4. Binance Coin (BNB)

• Market cap: £39.3 billion

Binance Coin (BNB) is a form of cryptocurrency that you can use to trade and pay fees on Binance, one of the largest crypto exchanges in the world. Since its launch in 2017, Binance Coin has expanded past merely facilitating trades on Binance’s exchange platform. Now, it 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 April 2023, its price had risen to around £249.

5. US Dollar Coin (USDC)

• Market cap: £26.1 billion

Like Tether, USD Coin (USDC) is a stablecoin, meaning it’s backed by U.S. dollars and aims for a 1 USD to 1 USDC ratio. USDC is powered by Ethereum, and you can use USD Coin to complete global transactions.

6. XRP (XRP)

• Market cap: £20.64 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 4 April 2023, its price reached £0.40, equal to a rise of approximately 9,889%.

7. Dogecoin (DOGE)

• Market cap: £11.3 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 April 2023, its price was at £0.08, up 50,636%.

8. Cardano (ADA)

• Market cap: £11.07 billion

Somewhat later to the crypto scene, Cardano (ADA) is notable for its early embrace of proof-of-stake validation. This method expedites transaction time and decreases 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.

Cardano’s ADA token has had relatively modest growth compared to other major crypto Cardano’s ADA token has had relatively modest growth compared to other major crypto coins. In 2017, ADA’s price was about 1.5p. As of 4 April 2023, its price was at £0.32. This is an increase of around 112%.

9. Polygon (MATIC)

• Market cap: £8.1 billion

Founded in 2017, Polygon—formerly known as Matic Network—is a relatively popular crypto. It’s dubbed “Ethereum’s internet of blockchains.” Maybe that’s why MATIC supports more than 7,000 decentralised applications (dApps).

Polygon has also experienced tremendous growth since its first launch. Today MATIC trades at £0.90.

10. Solana (SOL)

• Market cap: £6.5 billion

Developed to help power decentralized finance (DeFi) usages, decentralized apps (DApps) and smart contracts, Solana runs on a unique hybrid proof-of-stake and proof-of-history mechanisms 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 late April 2023, its price was around £16.68, a gain of around 2,827%.

Crypto FAQs

What are cryptocurrencies?

Cryptocurrency is a form of currency that exists solely in digital form. Cryptocurrency can be used to pay for 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 you can invest in cryptocurrencies, they differ a great deal from traditional investments, such as stocks and shares. When you buy stock, you are buying a share of ownership of a company, which means you’re entitled to do things like vote on the direction of the company. If that company goes bankrupt, you also may receive some compensation once its creditors have been paid from its liquidated assets.

Buying cryptocurrency doesn’t grant you ownership over anything except the token itself; it’s more like exchanging one form of currency for another. If the crypto loses its value, you won’t receive anything after the fact.

There are several other key differences to keep in mind:

• 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 you can trade 24 hours a day, seven days a week.
• 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 you may not be aware of the inner dynamics of your crypto or the developers working on it.
• Volatility: Investing in both stocks and cryptocurrency involve risk; the money you invest can lose value. 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’s tweet.

Do you have to pay tax on cryptocurrency?

If you buy and sell coins, it’s important to pay attention to cryptocurrency tax rules.

Cryptocurrency is treated as a capital asset, like stocks, rather than cash. That means if you sell cryptocurrency at a profit, you’ll have to pay capital gains taxes. This is the case even if you use your crypto to pay for a purchase. If you receive a greater value for it than you paid, you’ll owe taxes on the difference.

Are there cryptocurrency Exchange-Traded Funds (ETFs)?

Given the thousands of cryptocurrencies in existence (and the high volatility associated with most of them), it’s understandable you might want to take a diversified approach to investing in crypto to minimise the risk you lose money.

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

How do you buy crypto?

You can buy cryptocurrencies through crypto exchanges, such as Coinbase, Kraken or Gemini.
