how many total BTCD wallets are there that hold more than 50 BTCD? i would guess not much more than 500. of course distribution looks awful with this in mind. you only need ~84 BTCD to make it on top 500, which is barely more than 120$USD or ~0.36 BTC
i would guess that whales are accumulating BTCD in anticipation of incoming tech. if teleport/telepathy comes through...well, I suspect ATH will be surpassed in short order
Also supernet and sharkfund have some of these top wallets and these, like exchange wallets, are owned by a large number of people, along with the BTCD deposited in the MGW
My guess is that the vast majority of BTCD holders hold the coins on the exchanges.
