At this moment in time, the only "tax event" you need to be concerned about is money remitted into Thailand.
How you report the remittance depends on the "source" of the funds.
If the funds were entirely from profit, then the amount remitted to Thailand would be considered subject to Thai "income tax".
If you are a US citizen, like me, you will need to report your trading profit/loss on your US tax return.
If you have paid taxes on any moneys you remit to Thailand, then you need to refer to the DTA for your country.
For example, as a US citizen, if I remit to Thailand, and owe taxes on the remittance, I can deduct the taxes already paid to the US treasury.
You mention using Wise. However, this does not eliminate your obligation. It merely suggests that you could possibly "hide" it.
Not a solid long term strategy IMHO.
