0.26$/hour are great, especially if they are automatic and do not require active work. So if on average you are making 10$/h on your job, that is a 2.6% yield on top of your salary. For actions that sometimes may be even performed during traditional work that would increase even more the real yield: not under a numerical perspective but rather under a realistic perspective.
Besides I see a lot of you guys talking about this Splinterlands game so I think I will get started too to see the yield for me. Where would you suggest me to start from?
This is what people need to look at. Though, I earn more hourly than that, however it is only a 40 hour week. A constant 1% payrise that compounds isn't bad though :)
For the investment part, I don't even know! THere are so many sides to it. However, just start at splinterlands.com and see where it leads. You can always ask questions here and I or someone can help out.
