That plan got shelved mainly because we don't really want to get into being an exchange. There's a lot of regulatory implications involved in that. You might remember we used to offer ShapeShift deposits before they were forced to implement KYC. We are looking at alternative solutions to avoid high fees when the network is busy. At the moment Lightning Network still looks like it would be difficult to implement and there probably wouldn't be enough usage to make it worthwhile.

The good news, for now, is the mempool is clearing out and there should be many opportunities for low transaction fees until the next difficulty retarget (about the next 9 days).
