I'm inclined to agree with you... BTC is antiquated, even if it is the "grandpappy of them all." Whether it will end up becoming digital gold remains to be seen... but it's certainly not "functional."
My non-expert view is that the next wave will be the coins that serve some actual economic purpose, as BTC really has not been able to. Here at Steemit, we even have an opportunity... IF we can create an actual Steem based economy where the Steem token (or SBD) is used for actual trading in goods and services... not just as an investment to hold and profit from.
The economy is something that has been on my mind lately. Do you know any excellent programmers that can work in the steem blockchain by chance?
That good suggestion as well analysis
