Since the dump from 6500$ (and actually since sept.) btc dominance has been very stable, around 53%.
However it appears previous bear market phases always had an impact on the indicator.
How do you explains this at all?
Bitcoin has always dominated the market right from inception. 53% dominance is no longer surprising. This has always been the range of its fair share in the market. BTC gave birth to every other coin we have today.
