Yes, taxes are associated with buying, selling and trading cryptocurrency. Depending on your location, the type of coin you trade, and other factors, the taxes you may owe can vary. In the US, for example, if you hold a cryptocurrency for longer than one year, you will be subject to long-term capital gains taxes, whereas if you hold a cryptocurrency for less than one year, you will be subject to short-term capital gains taxes. It is important to consult with a tax professional for specific advice about your situation.
