Thanks for the responses. I wasn't really asking for how to do it, I was just asking if there is interest in such a service that would work entirely online..
Imagine something like a coinbase without a KYC, just anonymous.
Because there is something that is out there but not really known it looks like and I just wanted to post it here
I think it is hard to find an exchanges that won't ask for personal information/KYC if someone tries to convert Bitcoin into fiat nowadays since there's an issue about of AML using cryptocurrency. The only thing that I know that you can do is to find a buyer of your Bitcoin and do the entire trading personally or through online
but be careful doing it online, you might wanna ask some midman/reputable member here who can do all those things possible.
