It's a ponzi website, they used to pay before.
After that, they started to force user to upgrade their account by saying "hey, you have 2 account, you need to upgrade or we won't pay you".
Some user got their partial withdrawal after upgrading, and the others not.
This is what they do, so people like you will still believe they're legit.
That's not even a miner site, it's just showing you an animation, they're not even putting ad, how do you expect them to profit from this? Don't believe? Check your CPU when "mining" with them, or google them online.
Sorry for being straight, I'm just trying to keep you from loosing your money.
I confirm but if it is still paying it is still profitable. if he provides a collateral there aren't problems. he has some risks in every case but providing the collateral he saves the lender
