If I were Patrick, Donald, or Amir I would do everything in my power to maintain the integrity and profitability of Intersango to help them payoff their pending legal fees. If Bitcoin continues to increase in value like it has, Intersango could become a huge cash cow as it was one of the leaders.
What they should probably do is consider bringing in respected members of the community who can also infuse capital into Intersango to stabilize and legitimize the situation to tie them over this mess with Bitcoinica. I think they provide a valuable service for the community.
If you were them would you have gotten involved with Bitcoinica? If you did would you do a damn thing about fixing it? I think you have better judgement than them.
The way to have integrity and make a cash cow is not to overextend and get involved with projects you can't handle.
I never used them since I asked them a question and got the lawyer brush off six months ago, but if people are paying 15%+ to get funds off of a site immediately that's telling.
