I use only bittrex and binance. Tried this one previously but I am glad that give up soon after registration.
Bittrex has a bad reputation, besides, I had a problem with them. They blocked my account without responding to my requests. Binance is truly one of the best.
I believe Binance is a good exchange. From all appearances they have the technology, the funding, the support and the volume to be a good exchange.
Binance is not licensed anywhere, their offices and servers are in secret locations and the founder moves around all the time.
In many ways those are benefits. But it could also become an issue.

The advise remains the same. Keep minimal funds on exchanges.
We do already know on how they do operate. Their popularity increased due to that factor where they arent strict when it comes to centralized compliance and now they
have shown on the system for them not to be traced by the government.For now they are still loyal to their customers but we cant be sure on how long they would retain
this kind of system because sooner or later if they wont be legalized then they would go to the same path on most exchangers do.
