I think it is interesting that only 6.4% of the adresses have between 0.1 and 1 BTC and only 2.41% are between 1 and 10 BTC. There is a large gap between the small Bitcoin holder and the whales (0.01%) that own more than 21.38% of the total Bitcoins.
It is also understandable that there are more and more accounts from users that come from poorer countries that also want to invest in Bitcoin, but do not have the purchasing power to buy a whole one with the current bull market.
With the Bitcoin price as of (01.09.2017)at 4738$, means it is higher than the annual nominal wage of quite a few countries including but not only: Chile (4680$), Romania (4266$), Uruguay (4138$), Guatemala(3991$) and many more. reference.
Consequently many of the normal inhabitants will have difficulties purchasing an entire bitcoin. But the investment opportunities are high if they can manage to buy a fraction.
Where are you on this list and which country are you from.
