I don't believe so as I have already earn my first stake with just over 300 coins. I will say this I think it's best to split my coins up into smaller blocks of say 100 coin blocks because I didn't know it will take 641 confirmations before my coins can stake again. So if I have 3 x 100 blocks I can still stake while the other block matures as right now I'm still waiting on my first stake to confirm with still over 200 confirmations to go.

I like to get the dev's answer or anyone else here is it okay with 100 coin blocks? or is that too small for DMD?
