I'm assuming this is from fees for Bitcoin payments (not buying and selling Bitcoin itself in the Cash app, which is free). If so, and if the fees are the same as any other payment (2.9% + 30 cents), the amount of payments made in Bitcoin are somewhere around $1.2 billion? I'm sure my math is off (especially because I'm not sure how to account for the 30 cent figure) this is still a huge number, and not what I was expecting people were spending in Bitcoin to buy actual goods and services.
