Non sense. Your scenario would lead to a market of constantly cannibalising coins, no one could be a storage of value better than bitcoin, it is the IDEA that cryptos in general have value that gives bitcoin any value, not to mention the infrastructure behind it.
why cannibalising coins?
Bitcoin is not a storage of value - open your eyes - that's the core-problem:
it doesn't store value, it just burns value away
the infrastructure can be used by altcoins too. It's just a change of software.
after several years of competition amongst alts there will be a superior coin emerging and that one will be good.
bitcoin is the first - and also a gigantic pain in the ass
Having bitcoin around in 2020 would be like we would still be driving today with cars from 1910.
I am pro diversity, pro innovation and developement, pro profit, pro adoption, pro crypto but anti bitcoin sadly
