I think what I got out of it was that someone has a miner, and is offering people to use it, but they have to transfer 0.1 to a new wallet. They will then supposedly receive 0.5 BTC within one day? Seems a bit suspicious at the least.
It seems really suspicious because you cannot gain profit immediately just for mining using a miner hardware if that mining is legit one. Scammers offered this type of scheme because if they invest for an hardware miner itself they won't even have bigger returns as to be profitable in the future. So they are doing it in a ponzi scheme and this was really convincing to those investors whose mindset is an easy money, which mainly ended to regrets and worst experiences which is a big failure. Because of it most of the mining schemes really been gaining bad reputations and even those legit one's got affected, most of the people resist topics about mining because of those reasons.
