A few months ago I hardly sent invitations and referral links, because there was little response. However, like most things slow. and steady wins the race!
Nice job. I do think the sats loaded invite links are a great addition. I set mine at 1k sats. I think that's enough to entice someone but not so much that they will just collect the sats withdraw and never return.
Yes, perseverance and patience are the keys to success.
When planting seeds, the farmer needs patience to monitor the growth of the plants and wait for a successful harvest over time, while caring for the plants regularly.
