So guys, I've been staking Energi since 30.11.2019. Back then I received my share from their Giveaway of 110 NRG coins. I installed the wallet on my daily driver laptop(Ryzen 5 3550H, 16GB of RAM, AMD RX560 2GB) and started staking. I did post before my earnings, but, wanted to let you know about the results after little more than a month of staking:
I got 4 payouts so far: 2 on 20th of Dec, 1 on 25th of Dec, and one of 1st of Jan. All of with the same amount 2.28 NRG, totals of 9.12 NRG for that period. This is about 8% return per month, which is completely insane. I am even thinking of buying more NRG coins, but that plan is delayed by the fact that first I have other targets to complete, before I start put my money into NRG and something else I await for the right time to buy... for the coin to drop it's price a little bit. For best results:

One more reason for me to like Energi coin is that their team is very active and doing quite a lot of stuff and the coin will eventually benefit of in the future. For those of you who are interested I would suggest checking their website and their social media:
Those are the easiest places to keep yourself updated and informed what is going on with NRG and any new initiatives they might have.
Currently Energi has a bug bounty program that will pay up to 5000 NRG for critical bugs found on the testnet. Just imagine, 5000 NRG is about $10 000, which is enough for you to run a Masternode. And running a masternode is very very profitable.
Good Luck all and hope you find that information useful.
