@Bttzed03, thank you so much for bringing this topic up.

According to National Internal Revenue code "Lahat ng income galing man sa kahit na anong klaseng legal na paraan ay taxable."

Hindi nga masyadong klaro ang binigay na laws ng BIR subalit ayon sa kanilang pamunuan na ang pag tatax sa crypto income ay naka depende sa kung papano kinlasify ng BIR ang iyong bitcoin transaction. Pde itong maging capital tax gains or income tax.

But then again malaking part ng pag consider sa iyong possible tax yung tax reform. As long as you are gaining not more than 20,000 pesos monthly . You are not liable to pay your "Income Tax" in accordance to law. At when it comes to capital gains tax I will summarize it for everyone to atleast get an idea.

You are entitled to pay capital tax gains if:
-Binenta mo yung crypto asset mo
-Bumili ka ng producto gamit ang iyong asset.
Yan lng nalalaman ko sa ngayon.

I think this article is worth reading para naman ma intidihan nyo kahit papano.
