As of Jan. 14 we already have 784,000address that owns 1 bitcoin or more. The number is already had an 11% increase from 707,000 that is recorded a year ago. In 2015 has more than doubled. Most of the address came from exchanges and big player "whales" that usually hold a big amount of bitcoin.
This is pretty surprising actually.
You might expect there to be fewer whole BTC owners when BTC is worth a lot, and more when BTC crashes.
However, if you look at the charts for the last 1 year, Bitcoin is actually worth 250% more than it was this time last year.
This means that as a whole, the total value the sums held by whole BTC owners increased by the same amount over this time period.
I wonder if this growth will continue even if BTC hits $80k+?
