HI,
please access this website
http://bitcoinrichlist.com/top100 , we know 947 Bitcoin addresses control 50% bitcoins so far. it is too weird for Bitcoin business development. how to fix this problem?
Hopefully as the Bitcoin price rise these big holders spend more coins so the coins are distributed more evenly. And about 40% of Bitcoins still has to be mined, so you can expect these 40% to be distributed to much more people.
