There’s no easy way to buy bitcoin

I have been buying small amount per paycheck on Strike. Easy. I’d just transfer the sats once I have accumulated more than 0.1 BTC into my cold storage.

Yesterday I wanted to buy a whole coin all at once and have it transferred into my cold wallet immediately. Then I realized there’s no way to do it????

Those places I’ve used before all have daily/weekly limits on deposit and withdrawal, making a whole coin purchase and immediate self custody impossible.

Does anyone know how to approach this?
