The capital comes from the profits from other markets. Which comes from exploiting workers. The original investment didn't just spontaneously expose itself, people chose to flow money into it. They'll pay for the next bubble with the profits C-suit executives stole from their workers and the little guy. They will take what should have been yours and bet it away on some fever dream that was doomed to fail from the beginning. All in the hopes that they might make their wealth get more outrageously excessive before this bubble bursts and they try again on the next.
