According to my opinion, I think It's income and should be taxed. There should be a tax on capital gains because it's income and the current law is that people pay taxes on their income. If we want to debate or reform that policy, perhaps we should, but then it should be targeted at all kinds of income taxes, not just capital gains taxes. Getting rid of capital gains taxes by themselves is simply a way to cut taxes on the rich, because the rich make more money through capital gains than poor people do.
What is your thought on this matter?
I think it should be taxed, if the tax rate is high then it will be very frustating. We have responsibility toward our country but sometimes government too much extorting us. When you make profit in bitcoin then no other know that your capital is grow except you. And I think you don't need to declare your profit until you convert it into fiat money. Country should help the citizens to live in prosperity, and not to push the citizens to pay high rate tax which slow down the process to live in prosperity.
