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.
Of course, it is possible to stake on VPS, you should follow the guidelines of the respective project. However, all the basics are the same. I can give you one super easy option for start but it's not that secure and your funds might be at risk if your VPS account gets compromised.
Tips: If you are staking in your local wallet, simply import that wallet address in your VPS wallet. Activate staking in the config file. Done.
It should work in most coins staking.
