I asked chatgpt, and it answered that Bitcoin transactions are generally subject to tax, just like other forms of asset transactions. Tax requirements may vary depending on the laws and regulations of the country where you are located, but in general, the following situations may require taxation:
Earning profits: If you earn profits through the sale or investment of Bitcoin, these profits may be considered capital gains and are subject to tax. Salaries and wages: If you pay or receive wages in Bitcoin, this may be considered ordinary income and is subject to tax. Mining income: If you receive income from Bitcoin mining, these income may be subject to tax. Currency exchange: If you use Bitcoin to purchase goods or services, you may need to pay the corresponding consumption tax according to the laws of the country.
Oh yes, you have to pay your taxes bro if your country demands it and I always encourage people to pay it and not try to play smart in the name of Bitcoin. You may only get covered when it is about the non-custodial approaches, but when it is a custodial and centralised arrangement, you will be exposed. It could even be tough for the government to know if the centralised system is not registered in your country, but in the long run, what if you are a person of interest and you are later exposed? This could be sanctionable or jailable in many country's laws. The thing is that different countries have their tax laws as you stated but I've never seen a country that will exempt you from paying tax on investments, which makes it general.
However, if it is a gain from futures trading, it is still arguably not taxable in some countries, which makes the whole thing complicated. Because if you buy and hold your Bitcoin and also trade it in the futures markets, how do they differentiate the income when they are lumped together? This is often possible if the centralised company is registered in your country and cooperates with the government, they will be able to issue the record on that to the government to know which income to tax and not to tax.
