Inefficient Markets - How do people value a cryptocurrency?


Interested in hearing how people personally value a cryptocurrency. Would love to hear your personal thoughts.

(1) Do you hold any formulas? Valuation based on token velocity, market cap, transaction fees etc.
(2) Examining the recent DOGE surge, what are people’s logic or thoughts behind why the spike?
(3) Is it possible to quantify fervour, sentiment or beliefs (e.g. number of people of the HODL camp, ‘in for the tech’ or shill) and conduct analysis?
(4) Is it possible to accurately predict and make decisions with >0.8 accuracy on reports or sentiments on weekly price directions?
