BaseFEX is a derivative exchange that doesn't require KYC but has decent volume which is getting increasingly rare these days, among derivative exchanges.
They even have
made a page about it. hmmm ... why are people trying to trade at unfamiliar exchanges without doing kyc? If one day they cheated people and stole all the money, what would people think?
I personally find that exchanges too easy on traders to be suspicious. because they don't care about the interests of the traders, they only care about their money. KYC is a simple form, but it can protect your assets when you encounter a problem. We just shouldn't provide KYC for fraudulent projects but provide it to protect our assets!
