If Bitcoin succeeds (that is what it's happening), many other Crypto-Currencies can succeed as well (as we can see some solid AltCoins already).
Days work? What work? People now have confidence in other coins more than in Bitcoin, there is no measure here to tell % wise. And again, Bitcoin succeed in what? Its very naive to sit and think that everyone expects Bitcoin to succeed and than only alt coins will do.
I'm saying Day's work as an expression in relation to the trader and his "trading job". After the trader benefits from Crypto-Currencies prices to make profit, he converts the money to BTC again to keep holding. On long term holders prefer Bitcoin, instead of AltCoins that are used to make profit on short-term. Bitcoin's success is being built on long term, a solid progress being built slowly.
That is how I see the average Crypto enthusiast mentality at this point... What other coin do you think people have more confidence than in Bitcoin?
Well I am not against trading aspect, its clear for me. I question other things that is used to praise Bitcoin. I listed 9 things, in 3 pages only was discussed transaction fee and put LN as cure of all problems. strange is not it?
Are you really believe in magic?
Well, Lightning Network seems promising... I'm excited to see how it will affect Bitcoin's transactions.
I believe in technology's magic.
As I said, the solid progress is built slowly, there aren't final solutions overnight.
It shoudln't be a reason to be against Bitcoin.
Anyway, you are free to think what you want and to invest in what currencies you want.
