Most major economists on television and news outlets are saying Bitcoin is worthless. I'm going to use that "expert" analysis to do my accounting for trading Bitcoin. I don't see how they could tax your trades as the value of the coins fluctuate so rapidly. I think they are only talking about cashing out Bitcoin into fiat currency, but I'm no accounting expert. I will just play dumb as I don't plan on converting any of my holdings into cash this year.
Tax withdrawals are usually imposed if Bitcoin is exchanged for a country's money and is used to pay for something, it will indeed be taxed, but is it possible for Bitcoin to be taxed if not used for anything, and not exchanged into any currency, the answer is impossible the tax that will be charged is the buying and selling tax and asset tax, maybe like that.
