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 about taxation not only the government wants to take income from the owners of bitcoin, but it is possible to monitor or try to prevent fraud from criminals who use bitcoin for their money storage. And I think the tax taken is not too large compared to the value from the asset itself, so for the owners of bitcoin it's not a big problem.
