Though I'm on the same belief that 3000$ is a strong floor, I'd like to remind you that 5000$-6000$ also seemed as a strong support.
If the only thing determining the price was how many BTC are being bought and how many are being sold by people, I believe we would have never fell under $10k. But Bitcoin's market cap is so small it's easy to use the futures to manipulate the price.
Therefore I wouldn't be 100% sure that we've seen the bottom.
Of course, I agree that in the end it's just speculation and one can never be certain. But it's still a strong sign that we have managed to test the 3200 bottom twice since beginning of december with never reaching sub-3k.
It's still possible for it to get back to those levels, but I'd honestly be very surprised if it broke 3k after it failed during the much more bearish trend.
