Model one crypto buy and sell with total fees, signed profit or loss and an assumed tax rate. Entered prices are hypothetical, not live quotes.
One hypothetical buy and sell of the same entered quantity. Flat fees are total USD amounts, not per coin. Assumed tax = entered rate × positive profit after both fees; losses receive no tax credit. This is a scenario assumption, not a tax liability calculation: holding periods, jurisdiction, cost-basis rules, other income and losses are excluded. Entered prices are not live quotes or forecasts. Amounts are USD.
The first four signed amounts sum to the final net result. The final bar is their total, not an additional cash flow. All amounts are USD.
