With more than 11 thousand cryptoassets on the market, it can be challenging to know which cryptocurrencies are the most promising in 2021 – and which call for special attention of anyone looking to invest. For sure, the leading currencies (bitcoin and Ethereum) are still the best options, but other assets may represent good opportunities.

Polkadot, Solana, Aave, Cardano, and even the Axie Infinit game token (AXS) were the options considered to have the best prospects, according to experts consulted by InfoMoney. “Solana is one of the projects that have the most potential”, Transfero’s Director of Products and Partnerships, Safiri Felix, told the reporting staff. According to him, the most promising cryptocurrencies are those offered by Ethereum’s competitor platforms that manage to solve scalability issues. Check out the most notable projects cited by Felix and other experts.

Check out 5 promising cryptocurrencies in 2021

The five assets most cited by Infomoney respondents are indicated below. In addition to them, other cryptos mentioned were Polygon (MATIC), Chainlink (LINK), Uniswap (UNI), Compound (COMP), Filecoin (FIL), and PancakeSwap (CAKE).


Solana, the platform responsible for the SOL token, has been considered one of Ethereum’s greatest competitors precisely because it presents more agile, economical, and scalable solutions for smart contracts. The network’s scalability comes from its hybrid model, which combines proof-of-history (PoH) and proof-of-stake (PoS) consensus.

For Rodrigo Miranda, responsible for the Bitcoin University, the Solana differential is because it has Alameda Research behind the scenes, which also has a percentage in the FTX project and is growing in relevance.

2. Polkadot

THE DOT was one of the most cited tokens by the experts consulted by InfoMoney. The network, based on a system of interoperable blockchains (parachains), is considered by Felix to be quite attractive. “Interoperability is a high point. This simplifies the creation of products and services”, he said.

Polkadot’s protocol connects public and private chains, oracles, and other technologies that ensure transaction reliability.

3. Aave

The Aave project, from the coin of the same name (whose meaning in Finnish is ghost), is considered differentiated, especially because of its fast loans via blockchain. For Miranda, from Bitcoin University, Aave is a good asset “to diversify”. It is worth noting that the network uses the same smart contract technology as Ethereum.

4. Cardano

Cardano (ADA) is known for betting on scientific communities to seek solutions to the main limitations of the crypto market. The network uses different technologies, such as smart contract-based operations and the ADA token as currency.

According to Felix, there is a high expectation that the platform will start releasing its first smart contracts on the network, which should be reflected in a very positive impact on the asset’s price.

5. Axie Infinit

The confluence between online gaming and NFT has gained popularity because of its tokens (AXS), which can be exchanged for real money. The popularity comes from the fact that the player basically gets paid to play, representing a new trend for the gaming world.
