In my experience, there have been no problems. Whenever i sold crypto and took out the money, it usually showed in my account in minutes. The longest i waited was about 25 minutes, but most of the time it was really quick.
I lost crypto by mistake… i sent it on the wrong chain. They helped me a lot. They kept in touch for months while their engineers worked on a way to get it back, and eventually they returned it to me.
I know this process wasn’t just for me, but it was nice they stayed in contact all the time.
All in all. I great exchang.
