For the US Internal Revenue Service, this part of the income comes from Bitcoin assets and has been converted into non-Bitcoin assets, such as cash or goods and services.
The bitcoin assets you hold do not need to be taxed (at least for now), but as long as you use bitcoin to sell bitcoin or buy other things, there will be a tax return.
Bitcoin has been included in tax laws for countries that accept bitcoin as a net asset listed in the money source category. Some of my friends in the US say the bitcoin/crypto tax is around 19%, apart from being tested and strictly followed, the tax laws make no sense when you just buy and hold them but you let them. Go change and transaction, it will be taxable. Country-by-country regulatory compliance for bitcoin would be a good indicator of how bitcoin has evolved into a particular quantifiable standard. But that doesn't mean the US will be able to improve legislation that imposes increased taxes on cryptocurrencies that risk the balance - raising $28 billion in crypto investment. Lol
