Didn't understand your idea about "staking split size". Explain better and maybe we can discuss more about this.
Thank you for your reply!
Split size: now coin pile splits in 2 halves after staking. For example: 875 will add 25 and will split into 450 and 450 piles; later those piles will split again. In case I want to keep the min pile size 500, for example, I would like to specify in conf file something like "stakesplit=500", for example to prevent coin piles to split in piles smaller than 500 coins.
