For what it's worth, Gemini doesn't report everything to the IRS. This is the response I got from them when I asked last year:
"Gemini is required to report gross proceeds paid to US customers from bitcoin or ether sales on the Gemini exchange on IRS Forms 1099-K when applicable reporting thresholds are met. Typically, Form 1099-K reporting will be required by Gemini where the number of bitcoin or ether sales transactions on the exchange exceeds 200 transactions per year AND the total sales proceeds from all sales transactions exceeds $20,000 per year."
