Regulations saved the companies in those stock markets, not the stock market itself. The companies that leveraged their positions insanely actually lost a ton of money when the stock market crashed and right after that got saved by the regulations and goverments and they reinvested when the market was crashed and of course the new money coming in fixed a bit of the stock market which took time but the people in those markets actually lost a ton of money. So if cryptocurrency ever gets regulated I am 100% sure that whales will be saved whenever something bad happens and we will be the one thrown under the bus.
