This is all survivorship bias and nothing more, many other stock exchanges crashed completely
I presume that you mean cases where some violent upheaval caused property right violation, followed by the closing of a relevant exchange?
I agree that this is a significant problem. What is the real survival ratio for exchanges between 1870 and 2010?
However, let us return to the original point: that cryo would make people invest more in the future. Suppose I get a cryo contract and expect to be reanimated 300 years hence. Suppose that I am considering whether to invest in stocks, and I expect 33% of major exchanges to actually return my money if I am reanimated. I split my money between, say, 10 exchanges, and in those that survive, I get 1.05^300 or 2,200,000 times more than I invested—amply making up for exchanges that don’t survive.
