Incentives and finding different potential groups would do them a fair bit as it is now their volumes do appear to be stable around 420 BTC
Well, I mean not only that, but you would have to look at the fact that they don't necessarily cater to the "small" bitcoin purchaser... They seem to be more delved in the field of dealing with "big" bitcoin companies, but the reality of it is that there just aren't that much anymore or right now, that are located in the US. I think they would need to cater to the small man first before they go and try to sell bitcoins to the Bill Gates's and the Donald Trump's of the world.
