personally i try to invest in credible defi projects especially dex-es with relevant business model, as for now polkadot, uniswap are cool and i've found interesting stablecoin dex - xsigma, they are backed by a public company and it's likely they will be successful
btw heard about them, as far as i know they have cool opportunities for liquidity providers
thank you! i'll look on them and check - now i'm exactly look for interesting dex
