Napkin math, ofc the cost will need to be higher if not enough people pay, the cost to run the relay is 40k sats/day

Getting the pricepoint right matters if you want it funded.
You’re much more likely to find 100 Users willing to part with 12000 Sats per month (a daily sub is going to cost you more time in admin than it’s worth) than 1000 willing to spend 1200.
$3 per month is certainly doable. Trying to get 30 cents per month across 10X more users I’d be very sceptical of.
