Sorry to say that I don't feel bad for anyone who got scammed after page 3 in this thread.
I tried to warn everyone that this was most likely scam but people continued to send the OP btc.
Yeah, i stopped using them after i realised that they were using free tools available to anyone and charging money for it. You can actually submit a transaction of any size without a fee in viabtc's or antpool's transaction accelerator.
Worse, they seem to be interested in doing an ICO for this. And they are renting out ad space on their site as well.
I would not send any amount of crypto to them, for their service.
