Indium price just shot up. It may go up some more, go down, or go sideways. I currently own 50 grams of indium shot. I like to play with it, but I prefer not to chew on it. What if I buy, like, a few ingots and store them under my bed? This would be an investment of a few grand. Would I regret doing it in 5 years from now?

Possible reasons for regretting it: price plummeting, inability to resell without high transaction costs, being scammed (the density of tin is very similar to that of indium), the government confiscating it, getting indium lung, unknown unknowns.

This will be resolved based on my subjective judgement, so I will not bet.
