Here Are the Top 10 Cryptocurrencies of 2021

The past year’s crypto market can be summed up in three words: to the moon.

Bitcoin and ethereum, which entered the year’s bull run following big gains in 2020, both reached new all-time highs. The market capitalization of the sector swelled from under $800 billion in January to $2.2 trillion in December, according to data from CoinMarketCap.

Most major digital assets notched triple-digit percentage returns – easily outdistancing bitcoin (BTC), the largest cryptocurrency, which has risen 66% year to date as of Dec. 31.

But it was a slew of tokens that few investors had heard of prior to 2021 that dominated this year’s rankings.

A look at those top performers reveals three distinct themes: metaverse, “Ethereum killers” and meme coins.

Here’s a roundup of the top 10 performers among digital assets with a (year-end) market capitalization of at least $5 billion, based on data from the crypto-analytics firm Messari.

The metaverse became the hottest segment of the cryptocurrency market, buoyed by Facebook’s rebranding as Meta. Although the segment has sold off since its all-time highs, metaverse- and gaming-related tokens took the top two slots in this year’s Top 10.

Metaverse project The Sandbox narrowly edged out play-to-earn gaming giant Axie Infinity for this year’s top slot after its SAND token notched an eye-popping 162-fold increase. Investors bet on a vision where people would increasingly spend their leisure time in virtual worlds - although it’s still too early to say which virtual world that could be.

Rounding out the metaverse winners is Sky Mavis’ crypto adventure game, Axie Infinity. The AXS token was 2021′s second-highest gainer, soaring 16,160%. (That’s 162 times, for those who might get lost in the five-digit percentage figure.) Axie Infinity swept through countries such as the Philippines and Venezuela as the coronavirus pandemic left many citizens in those two countries unemployed - and playing Axie to earn income. Axie’s growth fueled the emergence of more “play-to-earn” crypto projects. Some industry pundits say these crypto-powered games could accelerate crypto adoption for the masses.

Complaining about Ethereum’s high transaction costs – known as gas fees – was another familiar part of 2021′s crypto zeitgeist.

Congestion on the largest smart contract-enabled blockchain sent users in search of more scalable blockchains, spurring the growth of alternative layer 1 blockchains and scaling tools. The year brought astronomical gains for the likes of Avalance, Fantom, Polygon and Terra, which ate up half the slots in the top 10.

These up-and-coming blockchains are commonly known as “Ethereum killers,” because they represent competition for the market leader.

Polygon, an Ethereum sidechain, notched third place, with gains of about 14,500%. The Polygon ecosystem saw a stellar year as it bet on several Ethereum-scaling projects and its decentralized finance (DeFi), non-fungible tokens (NFTs) and decentralized applications (dapps) users picked up.

Terra’s LUNA token also hit new all-time highs as the layer 1 blockchain surpassed Binance Smart Chain to become the second-largest DeFi ecosystem. The price of LUNA increased nearly 140 times, spurred by demand for the project’s TerraUSD stablecoin, which reached a landmark market capitalization of $10 billion this week.

Fantom, Solana and Avalanche - other layer1 blockchains - also cracked the top 10. The race for a more scalable alternative to Ethereum sent Fantom’s FTM token up 13,808%, SOL up 9,374%, and AVAX up 2,787%.

That’s not to say Ethereum didn’t also have a good year. Its native cryptocurrency, ether (ETH) gained a respectable 418% – six times the return for bitcoin.

While the rest of the crypto community sparred over Optimistic vs. ZK rollups or Punks vs. Apes, others pondered more serious questions - which cute dog coin will soar next?

Retail speculation flooded both traditional equity and crypto markets this year, spurring a whole new category of “meme coins,” including top performers dogecoin and DOGE-derivative Shiba Inu (SHIB).

Dogecoin’s surge began in the first half of the year, reaching its all-time high of $0.74 (with much help from the Twitter account of self-proclaimed DogeFather, Elon Musk). Year to date, the token is still up nearly 3,000%.

As DOGE mania waned in the latter half of the year, SHIB token took the spotlight, gaining 1,608% and taking the last slot in this year’s top 10. The success of DOGE and SHIB inspired several other tokens centered around the Japanese canine breed, including FLOKI, ELON, HOGE and DOGGY.
