There is no single solution which meets the needs of every single service provider. That being said having a hotwallet with 100% of the funds is simply inexcusable. More than anything else it is sad. Bitfloor was growing rapidly and was a great source of liquidity outside of MtGox (which is important IMHO). It is destroyed now and honestly shtylman is better than that.

That +1000. I t baffles me why larger sites have not implemented that yet. Hell they could even make it a user option.
