The government is always one step ahead of its population and of course they want to make a profit from everything. Perhaps if they could somehow help people who own bitcoins, learning, saving, safety, etc. and they would take a small tax for it, I think it would be normal, but in fact I am sure it will be on average 20%. 
I think that in my country the government is very reasonable and open when it comes to crypto taxes.
We only pay taxes if we decide to exchange crypto funds into local money and the tax is relatively low, only 12%.
If I can prove that I kept crypto funds in my wallet for at least 2 years I don’t pay any taxes.
