Why would you think you can double your money in 24h?
It is obviously a scam ponzi website, with fake number of 207861 investors.
And the trap was well planned.
OP sent some tiny amount 0.00069293 and they took the risk to give him 0.00138586 BTC
But when OP sent 0.00648236 BTC which is fairly larger amount then the first time he sent, they now just kept that.
Investment:0.00069293 BTC
Net profit: 0.00578943 BTC
They take the advantage of human greed.
I understood that OP got twice time profit from there
"a deposit of 0.00648236 and the 28th they will pay me 100%"if he has already agreed to gamble with this, this was the moment to stop.
maybe I'm paranoid, but I see a different scenario here.
OP clearly wrote how much he had invested the first and second time, but he did not write us the amount for which he was deceived and how much he withdraws the second time.
I would like that OP post here evidence, transaction ID's, just to be clear that really happens.
Why I am suspicious here? OP gives us an explanation that this crypto-emirate.ltd, obvious scam website, really paying first two times. so what are we going to think, hey why not just try once or twice, seems like easy money.
