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.
It's real Bitcoin does, no marketing, and no endorse. this point made the public has the result to directly pure confidence.
Adoption is lacking because there's no way to use the Lightning Network in an "easy" way.
you must know
custodial and how easy to use
There has been very little marketing thus far,
unfortunately, I never seen any marketing for that. are you?, explain me what marketing do you mean?, bounty? airdrop?
The Lightning Network is not used by any people because it's not easily accessible, and useable for newbies.
you must try it, same as you first time using myetherwallet,metamask,coinomi and other.
I for sure will try this out once it goes public. Been following the progress on the sideline, and it looks VERY promising!
