Earlier quoted context omitted.
My belief is that Mars will be colonized for ideological reasons, not for profit. A Mars colony won't be profitable. But it will be colonized, mostly for prestige, and also because of overcrowding & pollution, which will become bigger issues in the coming decades.
But why did you invest on those grounds? Is profit not your goal here?
My rationale is, when SpaceX actually launches the first Mars mission, the price will go hyperbolic. It will be the stock pump of the century. I estimated what valuation it would hit (~$5 trillion at the time), then looked at the current valuation, realized this will 50x in the next two decades, and concluded it would make a great investment.
