RC delegations will open the door for the world on hive. Power users can pay transactions for the users with RCs. Its a big deal because the inflation control in untouched.
A app like leo can use all there RCs for onboarding and value the own token more.
Same for games and other community. I also think its RCs can be something like venture capital, Investors pay the RC, Developer can build and user can use it for "free". I think really awesome business models can pop up with it.
Other "social" cryptos like bitcloud are years behind.
Yes, you are right RC delegations will be a big change/addition. I forgot about it. Thanks for reminding that this feature is being worked on.
Blocktrades doesn't think Rc delegations will be such a big thing. I have the opinion, every use case for Hive is a good one.
Besides the fact, RC delegation makes everything smoother ( if done well in code).
