Watched the first 28:10 just now. Will watch the rest too.
Comments: I am already doing exactly what Sahil explains, except that I don't trust a third party with my BTC (in his case, Level).
I pay for my daily stuff with fiat, just like Sahil does, mostly credit card and ALWAYS spending less than my income is, and I have some fixed monthly payments set on my fiat bank account by SEPA (like ACH). Just like Sahil does. And whatever is left after that, I stack sats with.
So the result is that every month my stack grows while I incur minimal fiat-holding risk.
Additionally, just like the host of the show, I do not trade BTC. In fact I can say that I have never, not once, sold one single sat. Never.
All this has little to do with what I was saying though, which is this constantly shilled idea that we have to pay for our daily expenses with sats. Which goes against the very idea of maximizing the growth of your stack.
