Scammers.
My first purchase was duplicated, so instead of investing 1000 I had 2000.
Then they sold automatically my ETHs when arrived to 700... Surprise! I tried to buy back, but then said I have no EURs...
When I complained they blocked my account, and after several weeks, they reactivated it and magically is working now. Of course, ETH raised and I lost most of my money...
A completely scam. BTW they are the same as GDAX.
