Bitfinex has had 100s of thousands of dollars sent back to them from Wells Fargo.I believe Bitfinex is considering paying out through a shell company not linked to them on paper
That won't solve the issue. It will only be a matter of time before Wells Fargo shuts down that route as well.
According to me, Wells Fargo can ask the account holders for additional fees (because of the high risk) or ask the account holders to shut down their account. Blocking payouts is illogical. If any of the account holders takes the legal route, I am not sure if this will hold up in court.
