At the conclusion of the meeting senior members of the Foreign Exchange Administration and Policy Department advised that due to lack of existing applicable laws, capital controls and the fact that Bitcoin straddles multiple financial facets the following Bitcoin activities are illegal in Thailand:
Buying Bitcoins
Selling Bitcoins
Buying any goods or services in exchange for Bitcoins
Selling any goods or services for Bitcoins
Sending Bitcoins to anyone located outside of Thailand
Receiving Bitcoins from anyone located outside of Thailand
Can we just agree that this might be what they said to him, that
they believed it was illegal, that Dave himself didn't (mean to) say that it was illegal, but in the case that it was, he closed operations just to avoid legal ramifications? I really don't want this guy to go to jail for some misunderstanding.
Actually, no. I am not an expert in Thailand's laws. I don't think anyone in this thread is.
However, so far as I can tell, they said no such things. It seems that OP asked the Bank of Thailand for an affirmative statement that these activities are legal. He suspended activities based, assuming everyone has been truthful, on the Bank of Thailand's NOT stating affirmatively that his actions are legal. They appear, in fact, to have reserved judgment for another time.
There does not appear to be any statement that any of these activities are illegal. While OP has possibly done us a long-term service in prodding the Bank of Thailand to provide some regulatory certainty so that business can continue, he might also have simply recklessly prodded a scary state entity to make a bad, hasty decision. I guess we'll see in a week or two. I'll judge the action by its results.
But nothing in Thailand that has any power to make laws has actually said Bitcoin is illegal. Goat is completely right on that part. The Bank of Thailand might or might not say that really soon, but it just hasn't yet. And if a central bank says something with legal significance, it says it on paper.
