Yeah, I know it might be a bit early, but I like buying just above previous support levels. If it goes down even further, I'll buy more at the next support level ;-)
Below $5k is a very big support level combined with the psychological price. It would mean around 75% discount, or if BTC hits 20k again, a 300% ROI. This will be a major signal for also 'newbies' to get in.
