DGB doesn't need lightning network to scale, but DGB DOES need use cases. Lightning's best use is not scaling, it's connectivity between chains through atomic swaps, which may well allow chains like DGB to process Bitcoin transactions by receivers of btc pushing bitcoin into lightning channels (spenders of btc need not even know other currencies are involved), exchanging to DGB, recording on the decentralized, trustless chain and confirming fast for little money. That brings foot traffic to DGB that we desperately need, takes a load off Bitcoin that it desperately needs and everyone wins.
Lightning networks are going to be huge in 2018 for none of the reasons that people are thinking about right now. As a smooth, perhaps someday, even seamless decentralized exchange that no one need beg to be part of (your chain just has to implement lightning networks), the smoothness with which users can move between coins will change the face of cryptocurrency.
Please, folks, stop saying DGB doesn't need lightning. Lightning isn't what you think it is. It brings an extraordinary host of opportunities to DGB especially, because DGB is so fast and affordable, that would take us decades to get any other way. Remember how google got started? Long before anyone went to their website, they were powering searches for directories like Yahoo!, which had a little logo on their page 'powered by Google'. Then they took over and the directories were forgotten. BTC could be 'powered by Digibyte' if we have a little foresight, and we could make the same leapfrog to the top google did.
If most people could see far enough to see, you are probably onto something…..DigiByte would already be a top 5 coin today!
We all learn by doing things wrong but eventually the right way will find itself even if we can’t see it.
