Hello Diamond community.

I’m hoping to partake in the PoS part of keeping the network secure.
What is the number of DMD coins that I need to make it worth while? What should be my expected ‘dividend’?

Two things I’m hoping I can get assistance on.
How do I get a DMD wallet up and running on Ubuntu (17.04)?
How do I import my existing wallet address?
How do I setup the wallet to run as a deamon on Ubuntu for staking so that it comes on automatically when my machine boots up.

I’m no Unix expert, so if you have very simple/outlined steps, that would be greatly appreciated.

Looking forward to being part of the DMD community.
