BTC can easily be used fort hosting for example or seedboxes and that sort of thing.
Yes bitcoin can be easily use for hosting because some website or hosting website are offering cheap hosting where you can pay via bitcoin i already tried this and its work good but i never use the hosting because i don't know how to use it i just tried to buy using my bitcoin lemao and thats weired.
I have paid for the VPN with bitcoin. It is quite a convenient process and make the transaciton quite anonymous for me.
