Back in the day, before r implemented rewards, people would just tip each other for useful/insightful/whatever comments in cryptos like Doge or Reddcoin, even BTC before it became too expensive to tip with. I know we can use Mastodon bots here, but I have no idea what’s available.
Someone could also make a new coin specifically for Lemmy. Maybe Beancoin. 😁 🫘🫛
look for crypto-positive instances and communities, there are some but not many. not really worth it right now imo.
