Why on earth start a bitcoin exchange there? More importantly for its users, why would you trust such an exchange?
We are the only registered business in Thailand providing bitcoin services, and have been in business for a year with an excellent service record (you will not find any complaints about our service).
Bank of Thailand has been in direct contact with us and everything you read about regulation in Thailand has probably involved our company.
You can read about the various changes in local Bitcoin policy here: http://bitcoin.co.th/news/
As to "why would users trust us":
1) We provide a 100% transparency proof of funds section here: https://exchange.bitcoin.co.th/info/transparency/
This allows you to verify any bitcoin or alt-coin address that we hold funds on
2) As I said we are a registered company and all deposits are made to our corporate bank accounts in our business name
3) Since we have had numerous previous dealing with the central bank I think this would put us in a better position for discussion if future regulation were to be imposed.
