Although this isn't new way to scam, but I want to remind it once again. Who know perhaps some greedy people's will fall in that trap.
Site is ugly, twitter screenshot is fake, transactions are all fake, block height that is being displayed is fake, double bonus for nothing
so I hardly think there will be anyone who would fall for this given the amount of btc they are asking for registration. Some might have fallen if they had asked like 0.001 or 0.002.
