an alternate explanation is that altcoins and ICOs were were bubbling for months, forming a blow off top, and a harsh correction if not outright crash was coming no matter what. everyone sitting on massive gains on thin order books at a time when the market could run out of greater fools at any moment---that's the context we're talking about.
if the news dropped in may or june, it wouldn't have made a dent in the market.
so sure, news is related. this is a market; anything that causes someone to buy or sell is related. i think the point the OP was trying to make was that people are always trying to rationalize price moves---"there must have been a reason, this latest news piece must be the reason." the truth is that markets are much more complex than that. the markets will move regardless of whether there is news. and bad news might help to trigger a crash, but the only reason that happens is because of a bearish market context where strong supply already exists.
