In the end, it comes down to risk appetite:
Do you accumulate patiently through the red season?
Or do you trade volatility and aim for quick profits?
These kind of months had always been my best month ever, where I grab the opportunity to accumulate as much as I can and prepare for the next greenish days. The month that follows after always have the highest percentage increase ever while leaving many strong holders in massive profit.
Also, during this time when the dip throughout September is over and different coins starting to show up, then the coins with good potential certainly exposed themselves, those with low background and no potential tends to remain at the buttom even when others has shown positive effects, track out those ones when September ends.
