It’s 1% of profits though, not 1% of your spending. If I go out to a nice dinner and spend $100, Strike and Visa split 3% for payment processing fees. To make that $1.50, Strike has operational costs that need to be covered, let’s just assume there’s $1 profit. Bitcoin core gets $0.01, a single penny, from that purchase.

I’m a fan of Strike and buy my BTC using their app as it’s the lowest fees, and I’m a huge supporter of funding Bitcoin Core devs, but even at scale the amount donated via this program is going to be minuscule IMO.
