They are highly correlated but certainly not lock step, see the 1 month ETH/BTC chart. Assets on the stock market are also highly correlated to each other, so I don't quite follow.
Seems easy to craft some counterexample, like "Doge acts as a marketing campaign for crypto as a whole and will lead to net-inflows to the BTC market".
That's fair, but I doubt it would deviate very much from the top 5-10, and that each of them would have significant differences from each other (ie not carbon copy clones). I would argue that most of the value in those top 5-10 was net-new and not a dilution of Bitcoin.
The notion I'm arguing against is that me creating MyCoolCoinX on the fourth page of coinmarketcap is somehow diluting BTC, any more than some new pink sheet penny stock is diluting AMZN.
Doge is an interesting case, in that it is the same tech as BTC with just some parameter tweaks. My guess is that most Doge investors are newer to the market, and wouldn't have otherwise invested but I could be wrong.
