"Apart from the 3rd place bitfinex wallet, top 10 addresses have unknown / private wallets. Even more interesting is the "Number of Ins" and "Number of Outs" columns, which shows how many BTCs went out of and into a wallet. Yes, they are the players who are now biting the bitcoins on the market due to FUD... A good example for these is the address on the picture. It can be observed on the chart that BTC was only collected in May, and after the exchange rate boomed, two-thirds of the BTC stock was cleared in time."
I am not so sure about the extended FUD theory on scaling debate (the original article has a strong conteo line in my opinion), and I can definitely know no information for that the owner of the given address is spreading FUD. However, the owner looks like a whale with perfect timing. And he or she has not bought BTC since more than a week. Maybe is a lower price expected?
