It all depends if they are competent banking lawyers, anything else doesn't matter, I have nothing against banking by itself, I just hate central banking propped up by governments.
It seems that they know the national and European laws and how to deal with the Austrian Financial Markets Authority (FMA). Other exchanges like Bitstamp (Slovenia) or Mt.Gox (Japan, Poland, Delaware) are more likely to be shut down by regulators.
It's interesting to see that the only exchange that offers anonymous deposits via Paysafecard or Ukash has built a secure legal framework for their business model.
