Well this is one point I don't agree with. Bitcoin core value is (as per Satoshi's White Paper) being a peer-to-peer electronic cash system and this core value has been proven many times over and again not to work as intended. True, workarounds (Ligthning Network) has been proposed, but still the bitcoin's core value has been devalued.
Don't really agree with that. First the fees are better again, since segwit finally start getting some adoption. Exchanges, that are still responsible for the majority of bitcoin transactions, are also being more careful the way they make the transactions (batching them for example) and this is having a great impact in BTC fees and speed.
This is not enough of course, and for that reason we have the LN that should fix this. Is not ready yet, but it's "close" (hopefully should be ready this year, since we keep seeing more and more LN nodes and channels on the main net).
The workarounds are needed, for scalability and I think off chain solutions are much better than the ones being pursuit by other coins, since those will result in a very centralized coin, and that was not the original objective behind bitcoin.
