Even all these ones do not give full guarantee that they may not end up messing anytime in the long run. None of these guys can be trusted, and if that is what one is looking for, then one would only end up being disappointed.

I remember how a lot of people have been giving bittrex a very solid review for a long time and then the whole craziness happened with the closing of accounts without notice and what makes other trading platform not to do the same thing later on in future ?
