I disagree on the 1st part. We don’t know all of them to guess what they’d be interested in. Bitcoin is the #1 cryptocurrency and many investors who’re interested in crypto would be interested in Bitcoin. Also some of these crypto firms actively search for good investment opportunities be it a project, app, or currencies. Maybe when they join & see Nostr booming they’d come up with new creative ideas and apps for bitcoin. Only time can tell us.
