There is no particular reason to think that 166 was the final bottom.
So you said yesterday. Proof?
Of course the only particular reason to think that 166 was the final bottom will be when the downward trendline is broken. That is currently 25$ away by my poor quality 'lines on a chart' TA.
You probably drew that line in linear scale, never draw trend lines in linear scale, they lead to fakeouts.
Also, breaking that line doesn't mean that the final bottom is in either. The same thing happened in May, it broke the downtrend trend line and price spiked to $680, but eventually made a new low anyway, creating a new downtrend line (the one I posted, currently sitting at $357).
Regarding volume in USD:
"Quote, USD"
^The bottom volume in USD is the same as the $475 megabulltrap.
Same for other exchanges.
