$ADA, I think after the recent announcement of Cardano, they are making great progress. Exciting roadmap and updates which will definitely pump the Cardano's price.

$ATOM, Cosmos is one of the important projects in the crypto market, which is very powerful. I guess they will break ATH in 2021.

$XSN, Stakenet recent announcement shows that they are doing unique things. They are developing a game-changing DEX, which is completely decentralized. +2700 Masternode will run Stakenet DEX. they are working on Lightning Network (For BTC) and Connext Network(For ETH and ERC20 Tokens) to solve the scalability problem. This DEX will make instant transactions possible with the lowest fees, which feels like a CEX! they will definitely break their ATH in 2021!
