It didn't "go" anywhere. The price of a financial asset is just the price at which the last exchange took place. I could buy a Bitcoin for $100K right now, and that would be the price, at least until the next transaction. Likewise, someone could sell one for $10K and that would now be the price.

In a thick market, one with many buyers and sellers and lots of transactions happening all of the time, you can be reasonably confident that if you go to sell something you will receive something reasonably close to the current price. In a thin market you may get a very different price when you go to buy and sell.

A persistent criticism of crypto markets is that they APPEAR to be thick but that most of the trades happening are just bots buying and selling on behalf of a very small number of actual participants in order to give the appearance of high volumes and that people will be in for a rude awakening if they ever try to exit out of a substantial position (the price they receive may be a fraction of the current market price, assuming they are even able to find a buyer at all).
