After reading @indigooceas comment under HF20 Update: Restoring Continuity, where she made an argument that small users still don't have enough RCs to interact enough, I came to the conclusion to write this post.
Because I understand the problem she describes, as the interaction restriction can be harmful for the growth of Steem.
Problem: Restrictive Limits For Small Users
If a user wants to write 20 sincere comments per day, then he/she should be able to do that and not limited by a limit of 10 comments due to RCs.
But on the other side: a user without any stake in Steem shouldn't be able to abuse this non-existing power, by being able to send hundreds of transfers.
Currently, the only way a user is able to gain RCs is by having more Steempower. Either by powering up some Steem or by receiving a delegation.
And I understand that there is the possibility of increasing the default RCs every account receives again (how it was recently done with 10x)
The Solution: RC Delegations?
But what if RCs could also be given by delegation - without the need to give away Steempower.
dApps like Steemit, Utopian-io, Dtube, SteemMonsters or even services like Smartsteem could delegate RCs to their userbase.
And the advantage of this method in contrast to increasing the default value is, that bad actor could have their delegation removed. Similarly, how @steem is removing SP delegations from bad actors.
On top of that, it would also create a market to RCs that will bring value for those owning a lot of RCs. Similarly, how people are able to delegate RAM, CPU & co. on EOS, STEEM would have it's own system of resources that can be delegated away.
And the best thing: RCs aren't a speculation assets - they have real value and will be needed even more as Steem grows.
RC Delegations Implementation Might Not Be Easy
Now I understand that the implementation will not be that easy.
As for example SP delegations currently include RC delegations as well. And if someone has delegated 90% of their RCs away, but none of the SP, then these SP have to be treated similarly how Voting Mana is used to check how much SP can be delegated (If you have 5,000 SP but only 50% Voting Mana, you can only delegate max of 2,500 SP)
But I believe that nearly every obstacle can be solved when enough brain-power is being used to solve it. And there is actually another big reason why I believe that RC delegations are the way to go.
Global Adoption For Steem As Payment
In my opinion, one of the biggest obstacles for Steem to be used as a payment form by many users was the fact that accounts were very much exclusive.
If I wanted a Steem account, I had to pay for it. And in comparison to other blockchains (BTC, LTC, ETH) where you're able to create a wallet for free in less than a minute, the fact that I needed to own crypto first to be able to buy an account or having to wait weeks to be confirmed by Steemit Inc. - is in my opinion a very big limitation for growth.
Now, with the introduction of discounted accounts, which are pretty much unable to transact but still can receive Steem, this problem has been resolved.
But an account that was only created to be used as a wallet, without interacting on the blockchain in social form, there is no need for Steempower. Such an account only needs enough resource credits, so they can make transactions.
And if RC delegations were available, Steem would be able to use it's advantages to the fullest (3 second transactions which are pretty much free).
I personally would love to use Steem for everyday purchases and now, with accounts theoretically being available for 0 costs for the user, this goal could become reality.
