With this dip, how would exchanges fare? Would this cause exchanges to declare bankruptcy? Which of the top exchanges do you think, is stable and can withstand a really deep bitcoin price dive?
Exchanges will continue on with their business... Any price hikes or drops won't affect them in anyway.
The people that are losing money are the people that are storing cryptos on these exchanges. Exchanges take a net 0 house position. Think of them as an escrow. Whatever happens they'll get their share of money.
And the real people at risk here with a price dive would be the buyers/sellers, who are speculating on the price going up/down.
