I agree with almost everything you said, but most of the time if you really look close enough, especially in hindsight, it's easy to see the technical analysis signals that would have brought the particular coin to a particular level regardless of how much it is affected by the price of bitcoin. Alts have definitely been unfairly hammered on due to wall street, and their paths would likely have been much different if had bitcoin's growth in 2017 been more organic, but the situation has made the technical analysis stars line up for mind-blowingly extraordinary gains in the near future for so many of them.
