StockBCoin is the company marketing, It appears. They do pre market stock purchases and sales. They guide you to what appears to be a banking platform Sottoc.com and that's where you put funds to do pre market trading. All goes well until you attempt to remove funds from the account at Sottoc.com. Then they tell you to pay a $42,500 validation fee, which they will refund, once they validate and then they will release the withdrawal. DON'T SEND THEM ANY MORE MONEY!!!!!!
