It's now being investigated by vietnam's regulator
This is probably best news I heard from this thread, which was full, for three years already, with naive people believing in this scam, trying to defend it, trying to promote it, trying to explain that Pi Network is actually a good cryptocurrency etc., etc., etc.
Somehow, it reminds me of One Coin and BitConnect. In their cases it also took the authorities a few years but once the legal procedures started they did not end. Curiously, One Coin is still alive in some parts of the world, where their scammers still believe that they can lure someone to buy their lies. The Bulgarian woman behind One Coin is still nowhere to be found. Let's see if the ones behind Pi Network will get caught. Maybe some other countries will also start targeting these scammers.
