It's evident that he is trying to scam. I wrote all those questions to everyone who may find this offer, not only forum members guests are from everywhere, to find answers to those questions before thinking to use it with real money. Those questions apply for all offers in this kind.
Good thinking mate, it's always needed to make others aware about such scammers who only want to steal money from innocent and decent people. Such people don't really care about anyone, they mostly target senior citizens of age 60+ because they find them as easy targets.
In case of Pi coins most users are aged below 60, so they in such case try to target youngsters who're not clever and who still trust such type of scammers. Only educations and awareness can stop someone being manipulated by the tactics of such scammers.
