You people obviously have no idea how asset valuation works. If people believed the price would be 300 in a few days, it would be 300 now. The current price is the best reflection of its future value.
From one angle you are perfectly right. But from another, some people have been able to predict future price movements correctly.
A simple example was the bubble. As the price went above $200, some people correctly said, this is a speculative price bubble, which will burst soon, and the price will subsequently sink below $200. In the event it went down almost to $100, followed by a bull trap, and some people predict that more bull traps will follow.
This is not only an asset valuation issue. It is also a psychological issue. And it is sometimes possible to foresee other factors influencing the price.
To put it in other words, if everybody believed the price should be $300, it would be $300 now, as you say. However, if some people believe it should be $300, while others believe it should be $20, then things are getting more complicated. It may take some time before one group realizes they were wrong and come round to the other valuation.
