It's far cheaper to run their current model, but at the same time they might lose a lot of customers to regulated US exchanges if they come to fruition. Interesting to see how things will develop.
If somebody is losing something then it is bitcoin which loses all of its functionality with this kind of harsh regulation. Seriously if this regulation is in place using cryptocurrencies like they are supposed to is more or less a crime. I'm asking this because the regulation states that even oversea exchanges have register or block access for NY citizens. I know bfx is sailing under some some obscure flag but whether they like it or not THIS WILL BE OF IMPORTANCE TO THEM.
