Why not take a look at Bitstamp, Bitstamp is a veteran international station in Europe, once ranked third in the world. The founder of BitStamp is Nejc Kodric. In October 2013, Bitstamp received a US$10 million investment, with Pantera Capital Management as the investor. However, in January 2015, Bitstamp was unfortunately hacked. Bitcoin worth 5.1 million USD was looted and the platform was shut down. Soon, Bitstamp was reborn after the robbery and has now resumed normal operations. I think it can still be trusted.
Bitstamp almost became Mt.Gox, how can anyone dare to believe it.
