I am calling a maximum potential low of $1500. However, I do not see a reason for which the price is dropping this sharply this weekend. If people were scared of August the 1st, dumping a few weeks ago made more sense (not 2 weeks before); not that there is something to be afraid of.
Bubbles don't make sense. They are blown emotionally and they burst emotionally. Markets are not efficient.
It's all psychology.
