You can buy stuff with Bitcoin using any wallet. Muun is a much better bitcoin wallet all around.

Strike is also a much better product than Cash App as a Bitcoiner:

- lower fees on buying and selling

- you can pay your bills with Bitcoin

- they actually track your cost basis unlike cash app

- you can pay LN invoices with dollars

- much better limits

Sure, the Cash App IU/UX is nice, but when it comes to functionality, it’s lacking compared to Strike.
