Thank you for sending Force towards my way 💜🫂 Yes, I think with more content and initiatives like #growNostr Nostr will be attracting more users. There should be completely free relays for newcomers and majority of users. We have to do better than the existing alternatives in order for people to move. If all relays charge, then "critical mass" may never come. So a free to use but "premium for more or faster use" model could work. In the future majority of the cost would be programming costs, the scripts to check spams and scripts to handle premium accounts. That could reach 1000 USD/mo. Lets say I charge 10 USD / month, I should find 100 users who would like to pay. However if a relay op wants to do less features he could charge less and offer less and do small amount of coding. I think "One time fee" model is good for spam but not very feasible in the long term. I would go for yearly or even 3 year subscriptions.
