Xchange.cx is the one I've been using for years now. No signup, no KYC, has all the major coins. Lowest fees I've found too.
If you're going to use it anyway, please use my ref link:
First ***** Cryptocurrency exchanger, no KYC/AML, fully anonymous.
xchange.cx
I'm not just shilling it to get the commission! It's a tiny amount anyway, the fees are low. It's genuinely the best instant exchange I've found.
