Do I have to report crypto on taxes?

The gains from trading and rewards are considered taxable income and must be reported. Gain (or loss) is the difference between the sell and buy price. Price is expressed in the fair market value in USD at the time of the transaction. When you sell (swap or exchange) crypto, it does not matter what you swap it for (another crypto, stablecoin, fiat). That you disposed of an asset is what creates a taxable event.
