Than using it as a currency, most majorities of people take advantages of Bitcoins as a trading asset. Under that point of view, simply, if the trader wants to earn profit, the price must go up.
Lets suppose a pump
$10,000 -> $20,000 -> $25,000 -> $32,000 -> $44,000 -> $52,000
Whats the peak?
The peak decides by the moment what? More people assume that there wont be a pump further. At the moment, people stop buying Bitcoins, demand reduces and price gets down
So, my question is,
Are there some "special" circumstances assisting people to think like that (there wont be a pump further)?
Indeed no one knows the peak until after the fact, otherwise all traders would be rich, but in reality only about 10% manage to hit it right...
Obviously the peak is a point where it didn't go further and then started going down. Doesn't matter if there are other peaks later, of lesser or greater magnitude. Just like mountains, each have their own peak, regardless of other mountains being taller or smaller.
Since you stopped at 52 lets assume 50 comes next, then 40, etc. 52 was the peak in that period. Doesn't matter if later goes back up to 60, that's yet another peak if it doesn't go further up.
So its just a way for naming an event after the fact. There are also valleys...
