I recently came across an interesting method another trader used to determine the FMV of bitcoin based upon the number of active wallets which held more than 0.01 BTC and a variant of Metcalfe's Law. Ideally, the value would provide the non-speculative value of one token (think M sub 0 when looking at monetary veloicty reports from places like the FED). So far it has accurately predicted the bottom twice in the two most recent pullbacks of BTC. I'd be curious to see if a variant could be used for HIVE as well.
