To get BTC anonymously I can only buy paysafecard offline and convert into BTC. Everything else can be traced. And in this forum I've seen most threads about this kind of exchange.
There is no such statement that anonymous people are not welcome here.
If you look in the Marketplace most transactions here are non-anonymous ones.
And nobody said anonymous people aren't welcome here. It's just not the focus here like it is on .onion sites.
