Well, nobody really knows where the bottom is. So, most definitely you can either say the true true true bottom If it goes below $20,000 right?
Nevertheless, everyone is just speculating with how Bitcoin would react to news and price forecast.
However, Bitcoin has been moving sideways from $31,000 to $39,000 last couple of days, and there's still a huge possiblity that $30,000 isn't the bottom yet, before Bitcoin bounces back to $50,000+ or hit another ATH.
All what we can do right now is to wait, things are extremely difficult, the market is moving in a weird way and it is unlikely things can remain this way for long, so sooner or later we will be given a signal by the market about the direction that it will take during the next weeks, if the price goes above the 40k level then this will be a clear signal that bitcoin will resume its upward movement but if it goes below 30k once again then there is the possibility the bear market has actually arrived.
