You don’t even have to buy on Strike then send. You can deposit fiat into your Strike account and immediately scan the cold storage QR code. BTC will be purchased at that time, thus skipping a step.

yes. That's what I've been doing right along.

Pretty sure that when fiat buys bitcoin or vice versa an exchange rate will apply bwo fees and/or price spread for any on/off ramp service you use. Strike and its business partners must earn revenue. 😎
