The news about the LN (lighting network) on main network of Bitcoin are connected with your its current high movement and with the altcoins correction?
Can be the LN the hangman for alts?
As I've said elsewhere, I think it will take significant market share from those altcoins that are nothing more than payment protocols with faster confirmations and lower on-chain fees. That's a significant sector of coins.
A well-functioning Lightning Network could make coins like Litecoin obsolete if they don't re-brand with new use cases. I suspect that many altcoin developers will re-brand and pursue features that Bitcoin lacks: governance structure, node incentives (LN rewards for typical users are likely to be
very low), alternative exponential scaling mechanisms like tree chains, consensus sharding and DAGs, and other full-service use cases like blockchain anonymity and decentralized exchange.
Yeah i suspect too that some alts will become obsolete, mainly those that just offer more speed in transations and low fees. I just do not know what the developers of these alts will do about it.
