Now is the best time to buy Bitcoin as it is falling
Actually the best time to buy bitcoin was a few weeks ago when it dropped lower than $60,000. But it's still a good time to buy bitcoin now before it goes and reach a new ath. Just try to accumulate as much before it creates a new ath.
The funny thing is when bitcoin price dropped below 60k$, I'm sure you or many others wouldn't buy bitcoin, but when the correction ended and bitcoin price recovered, people realized that bitcoin below 60k$ is a good time to buy. I believe that those who say the best time to buy bitcoin is over, they are the ones who will never buy bitcoin even if bitcoin falls back many times later.
As barisbilgili said above, bitcoin is a long-term and unpredictable investment so anytime is a good time to buy bitcoin. Don't hesitate and bargain with the market and when everything passes, we will say that the best time to buy bitcoin has passed. And if you are a short-term trader, a good time to buy will depend on your trading knowledge.
