The lack of adoption of Lightning network is as a result to poor marketing, this is what Ethereum does better than any project in the space, I think the team think they only need to build the network and users would rush using it when there are many competing solutions in the space.
Adoption is lacking because there's no way to use the Lightning Network in an "easy" way. In other words any newbie in crypto wont be able to make use of it. Stakenet changes this, and makes the whole network extremely user friendly to use, which will undoubtfully make big waves in the crypto communities.
