Is There Anything That Stops Users From Taking Out B to X Loans?

The product i'm curious about is the a, send one bit coin, get two bit coins back product. The rate you charges seven point nine % plus twoper cent administration fee. There's the point four between those two for the profit. That makes sense to me. Is there anything that stops users from trying to re hypothecate through the b two x? We don't send them the bitcoin, so it's like layaway, right? Yet like it, like wee.
