Minia questions / suggestions

I would like to know a few things about the Minia server and also suggest a few things that could be added in the future.

Questions
- How long does it take for the mines to reset and what variables affect the resetting of the mines?
- What are people's best ways of making money?

Suggestions
- Could there be some signs that reset mines on click (with a 2 or 3 minute cooldown)?
- Can there be keys and crates you can get when voting or at random times (e.g. 500 blocks broken) which supply rewards?

Just a few sayings to your post.
Minia has enough glitches already; and it will make it more glitchier when there will be keys and crates or supply rewards. Minia may be like prison, but it isn't prison. Besides, don't you think Matt will get more complaints about not getting their keys sometimes, when he is already very busy? Really, Minia is a simple game with lots of challenge...
But, you can vote at win.tmv.zone and earn diamonds. Well, thanks for reading this reply; and have a good day.
