this news and the way people are reacting to it is actually pretty funny in my opinion. not only because that amount is pretty small compared to the daily volume but also it was one a dump in one day but a dump in the course of at least 6 or 7 months which means the market absorbed it pretty nicely without any change.
not to mention that according to the news (the part which everyone is ignoring) is the dates. the sell off started last year during the rise and ever since the start price went up from $4000ish to $20,000 then fell. they always ignore this fun fact that price was rising even though this dude was selling, and yet they say he crashed the market!
