Short answer
In many countries, yes. Selling or swapping a token is often treated as disposing of an asset, with any gain or loss reportable. Rules vary, so check with a tax professional.
Tax authorities in places such as the US and UK generally treat crypto as property or an asset rather than currency. That usually means each time you sell or swap a token, you may realise a gain or loss compared with what you paid.
Frequent trading can mean hundreds of taxable events in a year, and losses may be usable to offset gains depending on local rules. Some countries treat very active trading differently again.
