Waves is not decentralized and is joke compared to Bitshares. Blocknet and Cobinhood don't exist and their tech is about 2 years behind where Bitshares was three years ago.
Sorry, I'm always on the lookout for a better mousetrap to invest in but there is literally no other DEX in existence that is even close to Bitshares for decentralization, adoption, liquidity, speed, etc. etc.
What I see happening is more shitcoins trying to call themselves a DEX to pump and dump.
