I used to do this until River offered the 3.8%. That’s about the same as the 4.25% MM rate on an after-tax basis. Not sure if the 3.8% is supposed to be taxable as well, but it didn’t show up on my River tax docs. So the net-tax rates are closer than you’d think, and it’s just one less transfer I have to make every month out of my brokerage and into Strike or River to buy bitcoin. From a qualitative perspective, I like it because it feels like I’m supercharging my normal DCA.
