I believe we'll go back to 2022 Bitcoin dominance by 2022.
The next halving should have put us past 6 figures, somewhere from $100,000 to $500,000 (to difficult to know where it will peak before the crash once we get past the 6 figure psychological barrier which is an huge accomplishment.. I predict tons of people getting rekt as they sell at $100,000 and open shorts expecting the price to crash right at $100,000)
By then the fact that most alts are scams should be obvious to even noobs and BTC will go back to the natural 80% balance as per pareto law distribution.
The alternative is there is a possibility we don't quite get past $100,000 and fall right before getting there, which would give us a a year or two of dipping before we actually get past $100,000 which will definitely crush altcoins.
80% + BTC dominance is not new in any way.
BTC was dominating cryptomarket with 80% + and above till March 2017, post which there was a steep decline in its dominance seeing lowest at 33% in January 2018.
Currently BTC is aiming high again with 52% + dominance on current date.
But again, comparing BTC dominance to BTC price does not always makes sense. Yes, it shows how BTC is dominating the market, but a lot many times, a high BTC dominance is a positive sign for ALT season.
The Mass first purchase BTC so that they can accumulate ALTs on BTC pair too.
