I have been going to some reviews of the top and best cryptocurrency exchange, but I am having some difficulties on verifying it to a real person on what is best cryptocurrency exchange that they use. Can anyone help me give some reviews of your favorite cryptocurrency exchange? and why?

Today, new exchanges appear almost every day. Some close or declare themselves bankrupt. Many changes to their owners. As its known with the advent of the new leadership, the rules change radically. What yesterday was still an excellent solution and worked like a clock - today is just a stock exchange with a bad reputation in terms of security.
Even my favorites have changed for the last six months. I'm very conservative.
Now are
Binance
Kucoin
IDAX
Huobi
