Dmytro Piatkivskyi started the following discussion on lightning-dev regarding the topic of channel rebalancing.
There has been a lot of discussion on sending cycle transactions to oneself to ’re-balance’ the network. On LN mailing list  or numerous places elsewhere. There has been even a paper suggesting a smart mechanism to do the re-balancing (see Revive or Liquidity network ). My question is what do we actually get from it?  states that the distribution of funds in channels does not really affect the network liquidity. I can see cheaper fees or shorter paths if the network is kept balanced. But don’t you think that a smart fee strategy will do the job?
To save your time,  explains the gist from .
