Bull market will be confirmed when Bitcoin has passed previous ATH (20,000+).
Until then, be careful, many expect a bull trap and further downside to new lows.
Maybe it's hard to reached that at a short period of time.
We investors wants to see a good price increase and we are seeing that today, BTC is still moving.
Even if we will not reached that ATH, I can consider this price action now as a bull run, at least in my own definition or judgment only
