The interesting thing about Bitcoin is ATH, people are motivated to buy because ATH's hopes can only be achieved so that they get a big profit, if New Ath can not be achieved anymore, I don't have a problem, people will continue to actively speculate to buy because of ATH's expectations even if it does not happen.
I slightly disagree with the statement you are saying, because in the past before there were many other cryptocurrencies on the market, those who bought Bitcoin did not remember ATH at all. Even those who bought in the past were purely because they considered Bitcoin to be the best cryptocurrency so they liked it even though they had no idea about ATH, what I meant by this was those who had bought Bitcoin before ATH happened like in 2012 and also 2013.
why didn't it happen?
bitcoin will go back up, and reach a new ath because of the speculation of those people who brought it up.
the thoughts of the people who made bitcoin went up again because they spontaneously bought it when the time came.
What raised the price of Bitcoin was not because of speculation from many people, but because many people already liked Bitcoin so that there were many people who dared to buy spontaneously with more mature consideration, of course. So the increase in the price of Bitcoin is not because there is more speculation, but because there are more people who dare to buy Bitcoin, after which they speculate in order to lure more people to believe in Bitcoin and buy it again on the market.
