before I want to ask you what is the lowest target for the value of BTC you want?
if 17k$ is still not low, hey man, look at the chart from 69k$ to 17k$, the percentage is down, it's really sad for people who bought bitcoins above 20k yesterday, but I'm sure their strong hand will win when btc returns to new ATH
It's never too late to buy BTC though, anytime of the day that's an opportunity but the most important part is when you know how to make profit from your investment. So anyway, I think OP meant to say was why Bitcoin isn't in the bottom yet or he/she just really wanna know what is the bottom price or when it could happen. It just shows that someone was impatient enough to endure this slow moving pace of the price as if this is how the market would move in the past.
It takes some time of realization that when you are in crypto space specially Bitcoin, you will need a lot of patience in order to get through to your objectives. Aside from that, $60k was the ATH before and here we have $19k... It makes me think, is it really not going lower?
