My interpretation is that the supply of bitcoins is now distributed among much more people than a
few months ago. We saw a lot of massive sales, where a single trader used to sell 10k or 20k bitcoins
at once. When this happened, the coins that were sold were distributed among many buyers; the result
is that the number of people holding bitcoins is now much higher. Of course there were a few massive
buys too, but much less; buyers typically bought smaller amounts, especially during the downward trend.
