I have noticed that the SOXX index, which is the NYSE Semiconductor Index, falls, so does the cyber currencies...otherwise Bitcoin is weak when the chip stock are weak....but also, I have been doing research and 700+?? digital currencies and other web sites such as Steemit appear to have formed one giant house of cards that has artificially inflated all currencies.....I would not be shocked to see a 50% to 80% crash coming soon across the board in cyber currencies...
