I don't think there will be a mass exodus from Costa Rica, unless something major forces it.
As far as books complaining about having to pay a license and not getting full banking priviledges, Costa Rica is not to blame.
All countries have correspondant banks in the US to expedite the cashing of USD checks issued, wires in/out etc.
The correspondant banks are getting the pressure from the US, who in turn are pressure the local banks.
Point being, I don't care what jurisdicion a book may bank in, if they stick out like a sore thumb, banking pressure will ultimately be there.
As an example of this, Belize has licenses yet I understand that Provident Bank in Belize, has kicked out a few books for this very reason.
Provident's main shareholder is Glen Godfrey, who owns the industrial park in Belize that is home to Carib, Ido and a handful of other online casinos.
