Thailand taxing crypto trading?

What about tourists (let's say 2 months in the country) who trade crypto online (illegal since no work permit) would these theoretically still be taxed or does this only apply to people tax resident in Thailand?

Commenting on those who live in Thailand but trade digital assets abroad, Mr Saroch said it's the duty of taxpayers to declare such income, otherwise they will face both civil and criminal penalties if the Revenue Department discovers the transactions.

Please interpret.

live in Thailand

Meaning tax resident in Thailand?

declare such income

To whom? Country of tax residency or to Thailand?

trade digital assets abroad

How do I trade digital assets abroad? Meaning physically being in Thailand but trading online using exchanges incorporated outside of Thailand?

Meaning, if one is tax resident in Thailand (let's say 200 days in Thailand per calendar year) and not doing any trading then being in a different country and trading... Eventual profits would have to be reported?

Extend? Law?

if the Revenue Department discovers the transactions.

How? Transactions on bx.in.th or what else?
