I think the most important thing for podcasters is choice and there needs to be both custodial and non-custodial options. Right now in my view there isn't a non-custodial option for podcasters that is easy enough for a mainstream audience that don't care about Bitcoin - but I think in the future this may change.

Ideally in the future most podcasters will onboard to a custodial podcaster wallet but then have the choice to move to non-custodial if they want to.
