nice reccomendations. i don't trade - only go in long term investment. first of all try to check business model and founders, it help to understand credibility of the project
i'm also not very trade guy) so these advices are ok. regarding defi, i try to choose interesting decentralized exchanges with good options for liquidity providers - at least the token inside could potentially have natural value
in case of dex - you also should check founders, whitepaper, business model etc; we all remember a lot of scam exchanges during ico period.. btw i found interesting stablecoin dex - xsigma, they are backed by a public company, maybe u know smth about them ?
