what about bisq then? aren't they doing the same exact thing pretty much? if the government wanted to shut them down it would be very easy to sieze their domain name by giving namecheap a call and contacting cloudflare who is hosting their domain name. for a service that is supposed to be decentralized, it doesn't seem to be setup with very much forethought to being resistant to usa government interference! anyhow, i know bisq will try and get off on a technicality that they never actually get sent money to send to someone else. so they don't think they are a middle man or something. i am not sure that's a strong enough argument to stop government encroachment...
Bitcoin is entirely decentralized. If you stay in Bitoin there is not a problem. Tying Bitcoin to the existing fiat system is an entirely different issue beyond the original bitcoin whitepaper.
I have not used bisq, maybe as it uses bank accounts and not cash in hand the feds aren't overly worried? Maybe it's not worth their time just yet? No idea, because they're not shut down doesn't mean they're in the clear.
