Again, you're confusing "mining" (economic activity that produces new coins and fees that happen to be measured in BTC) with "investment" (acquiring BTC via any means with the intent to hold). They are not the same concept, in fact they're completely orthogonal. You don't mine to get coins for investment, because you can get coins much (MUCH!) more cheaply via other means. You mine to get income in the present.
