Ah, and @Khaos77: All altcoins which reach a certain popularity will get the same transaction cost problem as Bitcoin. Even sooner or later with big blocks (if they are not gigabyte-sized 
).
). Bitcoin has a high transaction cost due to the dead end flaw of Proof of Work.
Proof of Stake does not have an ever increasing transaction costs to remain cost effective.
In Bitcoin , some rich elites you never met , secure the coins and continuing drive transaction fees higher.
In a Proof of Stake coin, anyone including you , can help secure the coin and not worry about escalating transaction fees,
because Proof of Stake is not a technological dead end like Proof of Work/Waste.
Considering LN offchain nonsense will record multiple transactions per second,
Proof of Stake will easily match it , and the reason is, Proof of Stake users will use modern PCs not depend on outdated tech like onchain bitcoin does, when LN will use modern PCs to achieve.
You should ask yourself why Bitcoin won't use Modern PCs when it solves the problems that core devs pretend only LN solves.
