I am not sure you even read it…
1) I mention Amazon specifically (even though it is the only one of the stocks back then that shows this profile, so 1/100) and I do say a few will have a V-shaped recovery
2) The article was written in November 2017
3) The bubble peaked about 1 month later and altcoins, on average, have lost 90%+ in value since then
So there is not much to disagree with. It’s history.
