To add to what’s already been said, the stock market (or more accurately, any given stock exchange) is by design a very liquid market – there are always buyers and sellers. The way this is achieved is by price. If there’s a shortage of sellers, the price goes up to entice more selling. If there’s a shortage of buyers, as is the case with this scammy piece of shit, the price goes down to entice more fools buyers.
As already mentioned, there are also traders tasked with buying and selling out of their own accounts to smooth out temporary imbalances. The whole point and value of an exchange is that you can always buy and sell, but the market determines the price. In the very rare case when there’s a large and persistent imbalance between between buyers and sellers, the exchange may temporarily halt trading in a particular security, for example to prevent a runaway complete meltdown.
