BTC Dominance has been rising since the end of 2022.
That's about 1.5 year.
We can find a similar pattern from Jan 2018 - Sep 2019 (little over 1.5 year), BTC dominance had dropped from Sep 2019 - May 2021 (about 1.5 year)
I drew the expected BTC dominance for next 1 year (white line)
Let's see the result after a year.
