If they can sell.
Liquidity on the bid side of things has not ever looked very consistent above say 800-1000 BTC for very long. Now it is at ~300btc or less.
How can one sell if there is not much liquidity to sell into?
Race for the exits is in Dash's future at some point. It is like a roach motel of crypto, you check in but you don't check out (if you do you were one of the lucky ones)
You're only looking at exchanges. Most of the significant trades (including $100,000 +) don't happen on exchanges, they are OTC trades where there is plenty of liquidity.
Exchanges modulate the prices at which OTC trades occur, so smoothie's point about the upcoming
Dash To The Exit stands untouched.
Your deflection about "muh significant OTC trades" fails to dispute, much less account for, the collapsing bid side smoothie noted.
Do you have any evidence for your assertions that
1) "most" significant trades don't happen on exchanges, and
2) there is plenty of liquidity in OTC trades?
