It should be underlined, no one knew that the rising Bitcoin price this year would be an ATH and that Bitcoin would fall soon after. Investors are investing in Bitcoin today because they believe it can offer significant returns and as a hedge against economic instability. They have predicted Bitcoin has a bright future, taking advantage of the current market moment can provide big profits in the future even if investing a small amount.

Investors believe Bitcoin is a safe store of value compared to fiat currencies such as the dollar, they try to anticipate the future when the dollar starts to weaken. Bitcoin always plays an important role in financial resilience when the economy is turbulent, Investors' trust in Bitcoin will enable them to achieve multiple profits in the future.
If you think investors have done something stupid by investing now, in my opinion, they don't want to make the mistake of not buying Bitcoin when they had the opportunity.
