Here is some info about them.

Cardano (ADA)

The first cryptocurrency review on our website was dedicated to Cardano. And not without reason. Cardano was one of the most undervalued cryptos at the beginning of 2019, and there are still reasons to consider it undervalued now. Here’s why:

  • Perhaps, the strongest team in the crypto space
  • Quality-first approach to creating a crypto that is secure and scalable by design
  • The upcoming release of Goguen (smart contracts and advanced interoperability)
  • Further development plans for scalability and governance

Litecoin (LTC)

Let’s get this clear. Litecoin is not the most scalable cryptocurrency. And Lite’s transaction fees are not as low as Stellar’s. So what makes Litecoin a good investment? The best answer would be the balance. The balance between tech capabilities and awareness (and, accordingly, adoption).  With Bitcoin’s transaction fees, users and businesses will look for something similar to Bitcoin, but more efficient. At the same time, for something established and common. From this perspective, Litecoin is the most obvious choice. After all, Litecoin has been out there for almost 10 years. Long story short, Litecoin is a Bitcoin alternative. Or, at least, there are enough facts to support this idea. You can read more about Litecoin and where to buy it here

Maker (MKR)

High volatility is one of the factors slowing down cryptocurrency adoption. Stablecoins, cryptocurrencies with a fixed price, are one of the ways to address this issue. DAI is one of stablecoins and Maker is a token that allows its holders to take part in DAI governance. Here you can read more about the Maker ecosystem to understand it better. To sum up, Maker is part of a unique governance mechanism that allows creating a more decentralized environment compared to other stablecoins. 

Algorand (ALGO)

Algorand is an ambitious project with a great team and significant attention from the global crypto community. Mainly, Algo focuses on security, scalability, and decentralization. The performance goals for 2021 are pretty intense, which indicates a good development pace and overall growth of the project.

From a certain perspective, ALGO can be looked at as Cardano’s competitor. Indeed, these two cryptocurrencies share some similarities. However, rather than being competitors (in a classic understanding of this word), these two projects are both bringing new ideas to the whole blockchain industry due to their open-source nature. And new industry-level ideas, undoubtedly, create great potential. 

Chainlink (LINK)

Chainlink is another crypto project with significant potential. The problem that Chainlink solves may not be obvious to an average crypto user. Let’s try to figure out why Chainlink is cool.

Chainlink is a blockchain-based oracle network that ensures the reliability of data input and output by connecting a smart contract to external data (APIs, other blockchains, etc). Simply put, Chainlink is an infrastructural project for smart contracts. Сonsidering the attention to the crypto industry in 2020, there is a high probability that 2021 will drive smart contracts’ development and adoption. And the more adoption smart contracts get, the more value Chainlink (and other similar projects) bring to the industry.     

If you like the idea of decentralized oracles, there is another project in this field—Tellor. You may find it an interesting alternative to Chainlink.
