Why would you pay 18000 USD ( a car, food for a year for some, food for 10 years for some ) on 1 virtual coin ( number in your phone or laptop )? That does nothing if you leave it in your wallet The crop on btc was collected at 60k now it has no more apples, the apple tree is dying...
The question you should rather ask yourself is why have people been paying far much higher for it previously, why have people fomo'd into buying bitcoin even when it was above 50k USD, so why wouldn't they buy now, when nothing changed, just the
normal volatility.
Your prediction just like some others in the past wouldn't age well, just to provide an answer to your question, people will buy bitcoin because of its usefulness in the society for btc enthusiast, it can do stuffs other than just holding or leaving it in your wallet.
Speculation / gambling ...not investment,also it's a pump and dump game that noobs do not know ...
