What is this, Micgoossens poor investment advice 101?
The first step in any type of investment is to quantify some type of fair value to see if you're getting a good deal or not. For example, in silver I can quantify right off the top of my head that even within the govt's rigged system of price suppression that highly undervalues metals, that the average gold to silver ratio is 47:1, and there's over a 90% historical correlation with gold to US debt. So the price of gold should be around $2500 even within their rigged system, and 2500/47 = $53 oz silver "fair price" within their suppressed, rigged system.
Of course, the GSR varies wildly and on the way to $53 it would create shortages, FOMO, etc, that would send GSR to 30:1 or lower and a price of $75 or more, so you have to factor that in too. Then, since silver is the most price suppressed asset on the entire planet, if the ESF suppression scheme fails, or fails due to the dollar losing reserve status, imploding, or some other issue since dollar reserve paradigm is what currently suppresses silver, that upside is instead stupidly higher at somewhere between $200-$600 an ounce in current purchasing power.
Then you can factor in things like cost of production such as posted here:

You can't. The price floor of bitcoin is recursive based on it's own demand. If there's no demand, miners shut off, and price floor goes lower. Such a thing is impossible in real commodities. Even if zero people are interested in buying lumber, silver, sheep, or whatever, it's cost of production generally remains the same.
Bitcoin is designed from the ground up to be a valueless pump and dump with no quantifiable fair value. This is why there's a Satoshi quote that says something akin to, "the value is either going to be high or zero". Because something with no fair value can be manipulated to face-melting extremes as long as there's some type of greater fools around trying their hand at the game of hot potato seeing if they can pass it off to someone else before they get burned, but it's also possible you run out of greater fools or casino attendees and it goes to it's intrinsic value of zero again.
