Bitcoin dominance is falling rapidly, which shows growing interest in Altcoins, especially top Altcoins which have enabled Margin Trading. From what it seems, the alt season has already started, but it might not last that long. According to my analisis BTC.D will continue to move down, towards 60% dominance till the end of this year. Then BTC might take the lead once again.... BUT, if the support will be broken, this will be indication of a growing interest in blockchain overall, and BTC.D might go down to 30-40%. This would be a true paradice for TOP Alts.
