How to give any valuation to Grin

I have given this question a thought one too many times and thought I throw out the question here:
What would be the valuation metrics you would use to value Grin 2 to 5 years out?

Is there any commodity of today whose value was predicted even slightly accurately by any valuation metric five years ago?


Of course, there’s such a large volume of poeple making calls that even if it was completely random someone would be right and it’s not completely random.

However ultimately there are only 3 calls that matter, up down and sideways; so I don’t even remember my own price predictions which have a large converage.
