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?

/edit: details
Since september Bitcoin went from $6500 to $5500
Then 5500 to 4200
Then 4200 to 3700
Then 3700 to 4300
Then 4300 to 3300

BTC and the whole cryptomarket are falling absolutely proportionately. It remains at 53%
Previously it wasn't the case. Dec 13 it fell from 96% to 87%. Strong movements in the markets pretty much always translated in a different dominance afterwards.

Note that the absolute value of btc dominance (53%), high/low, is not my point at all.
Also speculations on BTC aren't the point, it's only about understanding the current stability of btc dominance, if it has any meaning.
