They are a scam. I deposited 500 in BTC several months ago. AT first I saw and nice increase in by acc balance. It went from 500 to 635 in about three months. Then my balance stopped changing no ups no downs. BTC was up 100 per cent, and not change in my balance. I requested withdrawal and it was cancelled. I got a email stating that buy balace was too low and I did not consider fees.

Hello sir, i am not aware of this information in the support chat, though you should have received an answer about the cancellation of the withdrawal request . The fees are something you have probably discuss with your financial adviser, i will ask him to contact you so he will be able to answer your questions .

Maybe I will get 430 back, waiting. Best case is I will be out with a 70 dollar loss.
I would have been better off buying and holding the btc.
Stay away.
