Pi
1. Will Pl ever be worth anything?
It might be, but only when its mainnet comes out and it comes onto the open market. Even then, how much money it will be worth is a matter of pure speculation.
2. Is the PI crypto fake?
This is a tricky question to answer. What we can say, though, is that there is a lack of certainty about the system that powers PI. It can also be argued that its method of working is similar to multi-level marketing. On the other hand, though, PI does exist, it just isn't on the open market yet.
3. How much will Pl be worth after it is launched?
No one really knows. CoinMarketCap hypothesised that it would be worth about $94, but the mainnet has not launched.
