I think investors want a passive income, so encouraging them to engage probably won't work, but giving them passive options to leverage their holdings will. So a couple of things to promote
- The HP earnings (I think roughly 3%).
- The option to delegate to curators and receive earnings back, like @tipu (I think the earnings are about 10% p.a.)
finally, security, if your keys are properly managed the security can be bullet proof, but that's a steep learning curve for a passive investor.
The last thing to consider is, the powerdown period, is the 3 months lock-in worth the returns? I would point to something like crypto.com which has 3-month lock-ins, and they earn about 6% on cryptos, and 12% on table coins, so when comparing to this, its not a bad deal.
so there are lots of pluses, but don't expect them to upvote you anytime soon, they will probably delegate that.
