Is there adequate liquidity or is this all about to go upside down?

Okay, so I have a really serious question here, that I don't think that some people have considered. So, in order to exchange crypto for money, the exchange has to have the currency, so if there's a run on the exchanges and they run out of currency, then they can't accept your crypto.

You do all understand what that means if that occurs correct?

The markets are going to get almost instantly annihilated as people race to sell their crypto at any exchange that will take it.

I'm being serious here: Is there enough money in the exchanges to deal with a lot of people selling because I was under the impression that they, kind of sort of had to manipulate the crypto markets to keep the prices up in the first place by constraining them, so.

Is even asking that question a good idea? People probably don't actually want to know the answer, correct...
