I would like to know if it is possible to stake a PoS coin like Diamond or Hyperstake 24/7 from within the VPS. All I know is how to setup the same on it, but I don't how to make it run 24/7 as the more the wallet is open, the more chances of receiving stakes I will get. Any advice, tips or tricks would be helpful to me. I would greatly appreciate any help with this.
you do not do nothing, just open your wallet and close VPS. It will be work 24/7
But first calculate, will it profit for you
Exactly VPS runs 24/7 just start it and it will run. Better do backups though then have a copy of the wallet.dat just in case something happens with your VPS.
