Hear me now, believe me later... that base has not formed yet. And as such, any spike in price will be short lived. It needs a base to power the next run.
Have a look at how the bases were forming in all previous crashes. After hitting a minimum, the price bounces back up and sits there for a month or two, getting comfortable. So the ~500 range (or more broadly, 400-600 range) would, as predicted long ago, be the new base from where we take off in several months. But the downtrend is over at this point.
