I don't understand how people fall for Ponzi like these, if OP really wants to give away bitcoins for no reason, why not start a giveaway website?
Again. I am sure iT is not ponzi. You can see payment on blockchain.infoAnd.. again they might be all your addresses.
"Ponzi" doesn't mean you don't pay. It simply means that you pay your dividends using deposits from newcomers.
BS&T was a Ponzi that paid 1% per day for months. It still went bust in the end.
If you admitted that this was a Ponzi, that would be OK-ish, but you claim that you make the profits from "mining" makes it a scam.
If you make the profits from mining, why don't you keep them rather than giving them away to strangers?
And there are surely better types of charity for you than this -> so everybody assumes ponzi's and won't 'play' with you
