The answer is YES, you can.
We will be happy to assist you doing so. We will help you open a Foreign Bank Account. Then we will assist opening an account in an OTC platform.
Once you agree on the exchange rate, you can send your bitcoins to your OTC account. The OTC will then send you USD to your Foreign Bank account that we opened. OTC will give you an invoice and a proof of funds clearance. With this proof of funds clearance, the foreign bank will allow you to dispose of your money.
Then you can send the USD from your foreign bank account into Thailand and purchase a property.
