I don't want to insinuate anything. But Op, your offer is hard to accept. I it not a Ponzi even, you probably just take peoples money and leave with that. Do you have any proof beside your word, that you will pay?
thank you for talking politely,
proof of course you will see when there is one person who joined me and see I will send the profit
There is no real proof you can provide that you will pay. Not even a signed address with btc would be enough as you can always run. I wouldn't trust this at all.
