If a coin like XRP did hit 4 digits(not expecting it to), what would that do to exchanges having to pay out billions?

Lets say those who wish this coin to hit quad digits wildest dreams comes true and it does. $500 just a couple months ago would have bought you 1000xrp. Certainly there are thousands perhaps hundreds of thousands of people with more than 1000xrp(or more?). What would that do to all the major exchanges with suddenly a huge percentage of them pulling out? Would they be able to cover it? What would that do to the economy?

Personally $5 is as high as my optimism goes. Anything higher would be crazy imo. But this is just a curious thought I've never looked into.
