On-line casinos have chosen Gibraltar or is it Malta(?).
Iceland has an MP that spoke at bitcoin conference.
Panama has interesting privacy, incorporation, etc laws.
New Zealand, Singapore and Hong Kong (and others) have laws making it easy to set-up a company.
Finland had declared bitcoin legal (only in passing I might note).
Basically it is a whole cornucopia ... I've even noticed some operations are basing the machines that store identifying customer data in places that have hard private data laws, and the servers that do transacting, processing (whatever service the business it is actually performing) in other jurisdictions that just refer to the customers as non-identifiable numbers.
It is both for online Casinos - Gibraltar & Malta, but I guess that has something to do with wanting to be in an European Country.
What's an MP?
Yes, there is a shitload of tax havens on this planet - I doubt that Finland and New Zealand are really easy to run a bitcoin company. Anybody watching how New Zealand treated the Megaupload case? Bitcoin being "legal" might not even be an advantage...
I think its more due to the fact that Megaupload servers were mostly US based.
In any case one of the best jurisdiction for online casinos is Costa Rica.
