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.
It looks like the process of dominance getting started even from this year,now the dominance of bitcoin increases to 53% which is more than last's years dominance and most of the altcoins prices were dropping which shows that people were converting from altcoins to bitcoin but we also need altcoins as well to have stale crypto currency system.
