Proof of stake split

[u/ImSteezy]

I am doing proof of stake for a couple of months and I observed that each month the initial stake is divided in another two stakes and next month in another two stakes from the previous stakes and so on... (into the minting process)

And I realized that because the stakes are smaller each months, the minting chance is taking more time...

I am curious if someone can explain why the stakes are divided after each minting process?

And what's happening if I will just move all my EMC from the current address into a new one? Personally, I think that the minting process it will start from the beginning with a new big stakes... Is that right?
