If I mine Bitcoins in Mexico but live 100% of the time in USA, do I need to pay taxes in USA or Mexico?
What is the tax law regarding to bitcoin mining for Mexico?
You don't have to pay taxes for mine cryptocurrencies. Only if you sell them for fiat money.
As long as ou keep the coins and use them to buy directly with them, 0 taxes are paid.
This may not be true. My understanding is that IRS treat bitcoin as property. So when you buy other goods with bitcoin, you have to pay capital gain tax on bitcoin as well.
