I personally prefer to use a number of exchanges that have been known to provide security for the assets of their members / users so far rather than using new exchanges or exchanges that do not win the trust of their members / users, before we use an exchange, at least we should be able to know the level security in trading on these exchanges and of course this can be through references from friends or references from trusted crypto sites.
Strongly agree with what you say, because I also use a lot of exchanges that are already trusted, in this case I often take references on the coinmarketcap site, because the main thing in using an exchange is security that must be really strong, so that makes our assets safe, because binary-class exchanges can be hacked by hackers, let alone mediocre exchanges.
