Is it really that fast to set up Strike and start buying, or do you mean get them set up with something so you can send them some of your sats?

I've tried Coinbase, Swan, River and Primal. Buying through Primal was hands down the closest thing to an instant experience.

The point at which I typically lose people is "now connect it to your bank account." They seem to be more afraid of the exchange stealing their fiat out of their bank account than anything else.
