Czechia's 3-year rule: sell crypto tax-free

Crypto held for more than 3 years can be sold tax-free, up to CZK 40m a year
If your total yearly sales stay under CZK 100,000, they are also tax-free
Other gains are taxed at 15%, or 23% above about CZK 1.76m, with no social contributions
The holding period counts from your original purchase date, even before Feb 2025
