Japan and Denmark have the highest tax on crypto. It is on record that they collect as high as 15% to 55%, on crypto profits. I wonder the rationale behind these high taxes. I wonder if it is to discourage crypto use or to raise funds from taxes.  Such laws will discourage crypto investment and people will bypass laws by all means. But the good part of the Japanese tax law is that crypto losses could be deducted from gains in the future before taxes are calculated.
