Thank you Vega for your detailed information.
Unfortunately i have only 3 figures of LISK, so i assume i have to wait a few month to get the first reward haha

The good news is that the ROI for voting is (about) the same no matter how much Lisk you hold, it just takes a bit longer to get it.
Is it possible to stake Lisk with a Linux Bash wallet software? Would like to save energy by not using my normal PC for this.
Lisk is DPoS not PoS so you don't need to run a wallet for "staking".
