Bitcoin is now considered by the government as a property, not an income . This is the reason why they want to put taxes. I guess it is fair enough for those who earned hundreds of thousands here in the crypto world. But for those who are just starting to earn, the government should not. Still, I am in favor of the taxation. But the government should also consider the status of the bitcoin's market price.
i think if government will collect taxes from crypto then I should follow there rules as long as this will apply to all crypto investors. Maybe 8% is good enough for the tax in every trade you made. Although this will become headache to those who sell there bitcoin in a losing price as they will also fee there taxes. I hope the government can make a fair resolution on this matter if this will be implemented.
