Hydro(HOT) is a token that would facilitate transactions and liquidity for Decentralized exchanges by providing incentive mechanisms to users for providing liquidity and defining rules for executing orders. It competes with tokens like Bitshares which is over 4 times its price and has twice the supply of Hydro but Bitshares is also quite a bit further ahead in the game as there are DEX’s(like cryptobridge) already using it. Whether or not you will want to invest in this token depends on if you think decentralized exchanges are going to be the future or not. Personally, I think decentralized exchanges will grow in the coming years but I do not think they will replace centralized exchanges such as Binance, which will still have the lion’s share of the market. However, due to the fact that Decentralized exchanges have such a tiny fraction right now, I think they have a lot of room to grow and thus tokens like Hydro and Bitshares have a bright future.
