Come on guys as far as I understand the only way to do this automatically is to pay again and again the fee for smart contract execution.
This would be not very nice for people only stacking low amounts of USD-N.
Am not a coder or even able to read smart contract; being that said what I meant is maybe there is a simpler way, point of my post is asking support to change how smart contract works: for example ( I'm likely about to say something maybe totally unfeasable) sending interests coming from staking not to the waves address who started neutrino staking but to the "same place" where staked balance stays.
