Tezos

Tezos is a peer-to-peer distribution network designed to improve on traditional blockchain protocols such as those used by Bitcoin and Ethereum. One unique feature of the project is its on-chain governance, which facilitates code amendments to the blockchain protocol. Coin holders' ability to influence changes can help to prevent a wide range of technical problems, one such example being the Bitcoin hard fork that spawned Bitcoin Cash.
Tezos is the number 10-ranked cryptocurrency by market capitalisation. There is also a very well-resourced organisation known as the Tezos Foundation whose purpose is to support the project's ecosystem. It provides grants for projects aimed at strengthening the Tezos ecosystem.
Over the course of 2019, Tezos went from 0.41613 to 1.29277 USDT for a total increase of more than 300%!
