I currently have all three. Weather XM is giving consistent rewards, although low. I really like Nubila. It dual mines B3TR. I bought one Nubila and then bought another and a node with the B3TR rebate. They started paying out the rebates for the purchases over 12 months. I’ve had the most trouble keeping SkyX online, but it is user error.
I have heard some skepticism on this project around the idea that the information is already available. I do belive that the team has a plan to do it better with data above and beyond what is currently available. I would like to hear opinions of this group. Disclaimer - I have a 310 miner being delivered this week, so a bit biased.
WeatherXM is going to win out, but thats not saying a whole lot at this point
