everyone seems to misunderstand this graph..
it is to show percentages of adoption.. not population numbers.
lets say only 20 million people use bitcoin.
in the innovation stage (2.5%) =500,000
in the early adopter stage (13.5%) =2,700,000
in the early majority stage (34%) =6,800,000
in the late majority stage (34%) =6,800,000
in the laggards stage (16%) =3,200,000
this would total the 20million users. and would look like an S curve on a graph.. an S curve is a better example to use to show adoption.
as for the bases of noobs "true" value. the answer is BARTER. no its not a website, its not a ticker, its not a place you can goto. specifically its the opposite.
once sheeple stop fixing prices based on panic sales of an exchange that only moves 12k coins a day, and instead base their sell prices on their own costs and their own fair value. and how much the other person is willing to pay for your coins. you will have your own price valuation.
the places like localbitcoins otc private investment vessels are should NEVER be fixed to a single price based on another locations price. what there needs to be is 300 different prices and then a consensus of average value of the 13million coins in circulation based on that average.
EG ham burgers are not fixed based on the dollar price of mcdonalds in downtown new york. if you go to a mcdonalds in thailand and converted their prices into dollar it wont be the same. if you went to a mcdonalds in the UK, the price wont be the same. the difference between a mcdonalds hamburger in new york foodmall differs to that in a service stop mcdonalds at the side of a motorway/highway.
yet people pay it.
so people need to stop sheep following exchanges, as thats what happened when western exchanges that could not arbitrage china.. simply, for no reason but being sheep, followed prices down to $600 in january. and then when mtgox shut its bank account people sheep followed the price down to $450, before finally waking up.. if they did not wake up and continued to follow gox, bitcoin would be at $100 today.
so if bitcoin drops $10 on bitstamp.. and your on BTC-e. dont be a sheep and tank the price by $10 (same for vice versa).
my personal sources of price variety are from atleast 35 different locations of all varying amounts. but my previous post mentions atleast 4 of them, even if some of those are still sheep followers.
as for where i trade. well thats not in the list i gave before. and many whales along with myself are all still valuing bitcoin at $500+. and their is larger demand compared to PHP exchanges only fiddling about with 12k volume a day.
again. do not think that movements of thousands of coins should be a good source of valuing your coin or the whole 13mill+ coins. base your prices on your own costs and supplies. vs customers preferences and desire. use other prices only as a grey are not a strict price rule
