Is Binance a bad exchange? It's the most reliable nowadays. I completely understand concern about the recent hack, but it showed the full competence and funds reimburse, so no problem with it. Security is a top issue, but exchanges with reserve funds can afford minor fails.
I wonder, they ask question as if the exchange they are even using as done anything wrong to them. Since the time I have been using Binance I have never for one reason complain because I dont have any reason to. I have also not tried some exchanges for me to completely conclude that we dont have good exchanges.
For the fact that I have had a bad experience with an exchange does not give me the guarantee to judge other exchanges same. We still have people like Binance, bittrex and many of them that are trying to make things easy for people in this cryptocurrency market, so we need to learn to always still see the positive aspect of them.
