Local Crypto Tax - I'm confused

[myprivate]

There's some debate about whether we pay Thai tax on crypto gains in this example scenario;

Transferred THB 80,000 to local exchange 2 years ago

Bought BTC at 80,000 using local exchange 2 years ago

Sold BTC at 550,000 today and transferred the THB to my local bank account

I understand that we might have to pay 15% capital gains on the profit of 470,000 if we declare it in our tax filing, but some people say no.

 

But my main question is what if we transfer the same BTC from the local exchange to our Nano wallet today? Or we transfer it to an overseas exchange like Binance today? We are not actually "selling" the BTC and so I guess it is not yet "capital gain".
