Why would this even matter while we are in such early days of bitcoin? It's obviously undervalued if you're investing long term and expect to have a decent return 5-10 years from now.
If you're calculating it by comparing the prices of hardware you're not coming up with the real value but the lowest possible value that keeps miners mining. Why would the lowest value be the "real" value? You don't measure the real value of a car by the cost of parts and labor needed to make it. If we did that a lamborghini would be worth $50,000 instead of 500,000.
to answer you both:
value Vs price....
bitcoin is at what most would say is at great "value" right now. because the price is ABOVE a long tested VALUE. but not much.
take many things.
businesses tend to want to markup costs vs retail price at a 3x multiple. to cover labour bills and profit
(ya some get greedy and want more.. eg coffee costs pennies for ingredients but sell for over couple dollars 10x)
so if the acquisition(cost/base) VALUE is $5800 and the PRICE is $6400. thats not even 10%(0.1x), let alone 300%(3x) so people see bitcoin as very valued and at a good low PRICE to buy
however SELLERS see it under PRICED
the 300% markup retailers, industrials and manufacturers go by is normal..
100% to pay off the acquisition COST. 100% to cater for other expenses involved and 100% profit
consumers over the decades of retail psychology are usually happy and willing to pay out at 3x of a products cost for the convenience of not having to do the hard work of manufacturing things themselves.. its been like that since retail psychology began
even in bitcoin when costs since last year were $5800 or more. people were willing to pay upto $18k(3x markup) and then the desire slipped away at $20k
same goes for most things.
if you can work out the COST of something you can generally work out the zone of desire (as long as the 'product' has utility)
EG
if the PRICE went below $5800 its under VALUED
if the PRICE was in the $6k-$18k range. its in the 'valued range'
if the PRICE was in the $20k range. its in over valued
bitcoin is only 10% above value. but no where near over priced $18k+.
but value is subjective depending on which side..
the seller that wants $18k and the buyer that wants $6k
(value zone $6k-$18)
so $6400 is low value to seller but great value to buyer
(hope it makes sense.. i had a few drinks but tried best to keep my thoughts logical tonight)
in short: price and value are not the exact same numbers
