So, what's happened!?
what happened is that you are making a lot of
assumptions only to make the conclusion that you want. otherwise if you only move based on
facts you can see how wrong you are. and also your math sux
for example
(Total bitcoin held on wallet exchanges is about 2,200,000.)
Total bitcoin "lost" (figures vary depending on data sources) is about 4,000,000.
you don't know either one of these. you are only making a guess. there are a lot of exchanges and a lot of big services that hold a lot of bitcoin belonging to a lot of users. for example Coinbase coins are unaccounted for and they are offering service to millions of bitcoin users.
and the lost coins is just your pure 100% guess. and off the mark by a lot.
7,628,581,589 - 1,600 = 7,628,579,989 is the rest of the population! 8m between them equals 953 bitcoin each!
your math is horribly bad also
lets say there is really 13 million coins in circulation or what you call "live bitcoin" then 13000000
BTC/7,628,579,989 = 0.00170411
BTC which is about 10 bucks worth of bitcoin.
953 bitcoin each for 7.6 billion people means the supply is 7,242.8 billion bitcoin!!!
