If you don't mind me asking: what is your strategy for growth? will you start with courses related to bitcoin and lightning, since this is probably the most accessible userbase? do you have plans to onboard nocoiners? if so How will you get them to use Bitcoin/LN? I'm asking this not being a sceptic, but I see that people still have a pretty high barrier to entry, they have to download apps aquire Sats, and at least understand somewhat what Bitcoin is before their willing/able to start using it.
In your case, you mentioned earning sats by completing courses, maybe it's a viable way to airdrop some sats to first time users via free courses? Seems like a decent way to onboard someone. The course could even be 'How to use a LN wallet' Probably also easy to abuse though...
Or what do you think?
