Svonione, in answering your earlier question ONE PHONE ONE ACCOUNT, NO EXCEPTIONS. If someone games the system,  you BURN his coins. It is very simple,  really:either he bought them (and you know it) or he got them gaming the system.  You burn them -and the coins- and make the game FAIR. why does this have to be "like" anything? It isn't even crypto -which you continue calling it quite wrongly- but it easily can be fair because you can make it fair so no one not even you get more than 7 coins a day. Someone got more and did not buy them? Take them away and burn them. That simple.
