I'm surprised noone has pointed out the title's use of POS.
In btc context: PoS is proof of stake.
In common context: POS is Piece of shite.
And my two cents about using tor: after finding out that some exit nodes in Russia could implant viruses in downloads that the node was handling, I abandoned tor altogether.
Apparently its been remedied now, but that is a violation of my trust that will probably never be repaired.
