-Market recently over speculated on alts by greed and lack of understanding the nature of what a cryptocurrency is (2017) -It damaged Bitcoin and severely lowered its market dominance -Market seems to be readjusting the natural Bitcoin dominance -Alts could have plenty more downside remaining, Bitcoin probably has a lot of juice remaining -Punishment of the over greed and over speculative nature of alts, that attracted throngs of average joes -If you think useless shitcoins having a hundred Million $ marketcap is normal, you will be trapped again -Reverse = Alts/Btc bubble bursting
-Bear in mind that some alts are more resistant/stronger than some others, please do your own research -Bitcoin is a strong nascent asset that punishes over bearish behaviour since 2010: wether people short it heavily, wether people over buy alts hoping to make money VS Bitcoin or even Usd, are punished.
