Well, I've heard about asteroid mining where they could potentially mine unlimited supply of gold too. Probably won't happen in my lifetime but something to consider for your kids/grandchildren.
While cryptocurrency supply can be unlimited. Those that are useful are limited. This is reflected at why bitcoin is at 5k+ usd a coin and why xyz coin is worth peanuts.
