"Fool's Tax" is when someone pays too much tax, not doing due diligence, being ripped off, not being thorough enough etc.
In Germany, tax is not charged on crypto earnings if you hold them longer than a year.
However, the Cologne Fiscal Court did not follow the arguments of the plaintiff and had dismissed the suit in 2021.
In his income tax return for 2017, the plaintiff declared a crypto profit* of around $3.6 million.
If you keep your cryptocurrency profits in Germany for more than a year, there is no tax due on them.
