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 don’t have eyes on every exchange out there.
