Absolute nonsense.<p>If someone could make this device and run it cost effectively, what incentive do they have to sell it? Last I checked, the only place to make money on crypto was certain areas in China with very low electricity costs.
Hey guys, I am also quite skeptic person, but you judge a product based on an advertisement.<p>Ads are something for easier understanding. I went trough wp, it says that is someone use their sidechain for private BTC or ETH transaction validator will receive a transaction fee in the same currency.<p>And regarding ROI, here you are right, it's impossible to evaluate how much you can earn with this node until the token is on open market.<p>The same was with BTC, the same was with ETH and so on. You never know which project will be next one ;)
