There are many of it, and top-lists of top DEX exchanges are appearing often as well (here's an example for 2019). After reading one of the latest articles about it, I started to think -- there's too much info and not all of it is trustworthy. Reading reviews, comparing fees... I'd like to know which DEX platform you use and how did you make a decision about it?
Could you tell if you stick to one particular platform or use several of them? What criteria did you rely on?
I really like that you say not all the information on decentralized exchanges are trustworthy. This is actually true.
Not everything that is called DEX is truely DEX. Decentralized exchanges should be well decentralized in my opinion for it to be considered safe. So, Google "the most decentralized cryptocurrency exchanges" for recommendations. Before you start using the recommended ones, make sure they are actually decentralized and not partly decentralized. It should be decentralized, trustless/permissionless etc
