Poloniex is an exchange with several assets listed, they are very same, perhaps one of the exchanges with more assets, among currencies and tokens, listed to be able to trade, and in many pairs. Now, even with this favorable point, Poloniex still does not pass much confidence, at least in my point of view, in terms of: security. I do not see a concern on the part of its members to improve the security of the user registered on the platform, and that still makes me afraid to recommend or even use Poloniex more assiduously.
