good news. Guys, need i to mint exactly before snapshot to maximaze my reward or i must to do it earlier?
Just mint before the snapshot. But you have to sure your total balance of PoSToken actually increase successfully before that time.

Yeah ! But If I were you, I will mint tokens 1day before the snapshot will occur just to be sure that your balance token will increase also for the reward to increase. We need to safety first hehehe!
