What is the top 10 exchanges which all the investors trust it?
I can say that Binance is the king for me but still all of those exchange have their own flaws. It really depends on your experience, what exchange provides you better service than others. As I remember binance has an issue before even if it was sonehow leading. They are being hacked by someone on the year 2016 i guess and a lot of money are lost. However, its founder was professional enough to handle the situation and was transparent on what happen so I believe that Binance was the number one for me.
Binance has been talked about a lot in the past few years, and this exchange makes me feel very comfortable to use it, so far there hasn't been any problems with me. However, in the past this exchange has been hacked more than 7000 BTC and that makes me a little worried about keeping money here. This is still a reliable exchange and should not worry too much anyway.
