So it's been 3 days, and I have 200 mstem. What would be better. Send myself .1 mstem or 5 or all 200. I'm not sure how this works.
I don't believe it matters for this type of coin. The "staking" of it only involves that time you have them in your wallet and the total amount in your wallet. If you send more you'll just be paying more gas for the same reward that comes in.
Dev, please correct me if I am wrong.
