They just get stuck in Phase 2.
You said "coins become nothing or vanish", look:
so pretty much your coins are stuck in phase 2 and become nothing or vanish...
Now you don't think coins "become nothing or vanish". Ok, what does it mean "they get stuck", what happens to PI then? "Stuck" how?
We already know Bitcoin is a scam!
They ask "miners" to provide them private information to get coins and you call bitcoin a scam, lol. Who is "we", btw?
