Base on recent-historical trend (after Aug 2018), the BTC.D trend is again crossing a major FSBGB level (the thick grey line). Will this hint of a minor AltCoins season soon -- with BTC.D dropping to at least ca. 63% or even 58%? Perhaps this might play out with simply BTC falling significantly more than selected AltCoins (especially high MCAP ones) -- see my other published ideas of the possibility of BTC dropping as low as 8400 base on my FSBGB indicator >> tradingview.com/v/N0FyoIlB/
Looking at the Ichi-cloud and BB, it is likely the drop down to 8400 might be for only a relatively short period (either a wick downwards then up, or going sideways for a relatively short duration, up to 2 weeks, to get rid of weak hands and for smart buyers to accumulate) before heading back up again. Perhaps more (selected) altcoins will pump during this period.
