It is a SCAM.
I invested there some coins and got a min withdraw 100btc

.
Now it stands : 3 withdraws per month. So i`ll se in a few days what`s next.
It is not a scam if you know how this work. It is just risky gambling, your risk that if you can't pull out before it collapse you lose.
thats scam not becouse you can loose your money its because the min withdraw is 100 btc what is 24000 dollars
