Oyster Pearl - PRL is a little known coin (market cap of around 130th place i think). I believe it has a lot of potential to come in the top 50 area. It is a cool project for decentralised storage, where website owners can use the platform instead of ads (utilises some of the visitors CPU, but not obnoxious amounts like Monero mining - like the amount it takes to load an ad).

Also worth noticing they have coinburn coming up in around 10 days, and airdrop in April. Testnet is already online, Testnet B coming up in next weeks.
