Tell me what will the price be by the end of today? How about by the end of this week or month? You can't, can you?
If everyone can predict price of Bitcoin correctly, everyone would have become billionaires now, 16 years since Bitcoin Genesis Block in January 2009. The fact is not everyone are millionaires or billionaires from Bitcoin mining or investment since 2009, this means people mostly made bad and inaccurate price predictions.
They failed in the past, and will continue to fail in future with price predictions.
In financial market, as the saying goes "Don't time in the market" and it is applicable with Bitcoin market too as history proves it is good advice.
