I know that representatives of the Dominium team are reading this forum. And one person, whose name is demirtasilker57, appears here as a member of the Dominium team.
If you are really responsible people who want to honestly run their business, then do this - just apologize to those who were deprived of honestly earned coins, restore balances, say that it was a misunderstanding and the new rules were mistakenly introduced for the old participants. And the conflict will be settled. You will keep the good name and reputation of a reliable company. Everything that you are doing now, trying to find ridiculous excuses for your actions towards the project participants, causes people to misunderstand and want to avoid participating in your project. Do you need this? Make a responsible decision and claims to you will be removed.
