First off, just wanna say great list!!!
You may wanna add details about if its still possible to use the exchange without verifying their account, the corresponding withdrawal limit if yes and maybe you could also rate their transparency?
Non-US BitMEX trader here.
A few leverage trading sites that I know are not actively banning US IPs RIGHT NOW & SO FAR requires no KYC:
BaseFEX
Quedex
KuMEX
The issue with Binance isn't US authority requiring KYC. It is some more complicated legislation which essentially requires all American leverage traders to only trade on US-based, regulated, taxable exchanges. But they dont have eyes on every exchange out there.
Wow, I didn't even hear about BaseFEX and Quedex before. I'll soon be adding those three exchanges to the comparison, thanks mate!
