admin escape
Oh my gosh people do not learn. Shefchenko, the admin and I and a bunch of other people who actually understand how a game like this works has said a million times that you can't just deposit any amount that you want and expect a return. 0.1 btc is a lot of Bitcoin and there's a much smaller chance of you earning a return than if you were to deposit 0.01 btc or even 0.001 btc.
A ton of other sites work the same as this one except this is longest running ponzi that I have ever seen.
Next time watch your investment on the site. If you see the payment should be made but there isn't enough in the wallet to cover it then you must do a few things. You could invite friends before to ensure a payment. Or, if you really don't want to lose, you could deposit enough on the site to allow it to pay you and then you'll have more time to invite friends. Think of it like an unlimited extension.
This game is not a game where any amount is doubled or multiplied by something. Any site that claims it can multiply all amounts of btc is a scam. Make sure your deposit is calculated precisely to be able to earn a return.
Thanks and have a Happy New Year and a very prosperous 2016.
