With this analysis, I did the inverse of the BTC dominance. What you are seeing is the inverse BTC dominance.
Isn't this chart bullish per se?
Well,
1) We are below the all-time high of 2018
2) Look at the choppiness index (compare it with the 2017 bull run)
3) Finally, check the 200 weekly EMA (we didn't even cross the log growth curve yet)
To sum up, I see 2 other upcoming pumps for alts and potentially we will ends up in the 22% dominance at the end of the bull cycle.
