Many countries allow special treatment for gains made on assets that were held for at least one year for example:
USA applies a reduced capital gains tax rate
Australia allows a capital gains discount
Germany does not charge any tax on such assets
Koinly will show you gains from coins that were sold after 1 year of purchase as "long-term capital gains" in your tax report. This makes it easy to apply a reduced capital gains tax rate or discount on such assets.
🟡 Note: Unlike the above countries, reports for Luxembourg will classify sales as long-term if they were held for more than 6 months and Croatian reports will classify sales as long-term if they were held for more than 2 years
