Absolute time wasting, do not go near them, they are not legit. I lost 2.3btc, after months of trying, I hired Birman law to handle it as they seemed, unfortunately that was another waste of time, I had to allow my cousin venture into the darknet and he got me a blackhathacker who crashed them and recovered my money. It was nice receiving my bitcoins back, I happily gave his cut to him as agreed. You can write him at petru at hackwithme, tech. He’s extremely efficient.
