I only ever used trust wallet dex feature. I was just wondering how should I go about learning how to use them correctly? Also, any safety concerns or anything that I should be aware off? I would like to try some type of defi or anything else that would be useful to try/learn/use etc.
There isn't much about "how to use Dapps correctly".
Dapps are just apps which run in a decentralized plataform. There are many kinds of Dapps, from DEX to games.
Games are usually very boring, like Cryptokitties or something else NFT related. Basically, all Dapps so far are focused on financial transactions somehow, as even NFT are most used to speculate and make money.
