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.

Even if you mint one or two days before the snapshot (like now) you won't really lose very much. Better stay safe than sorry

Tomorrow is probably the best day

If we take into account that not everyone produces the token, then the issue of tokens goes much longer. Tokens in circulation will be less than planned.
