Isn't there only 1 account with over 100k BTC?
Either way, 5k is 2.2 million dollars so it's far from "nothing".
I read somewhere that uncle sam is the biggest bitcoin holder out there since the FBI confiscated all the silk road bitcoins. I cannot remember the exact figures but it would not surprise me if the account with over 100k BTC was the FBI one. Someone on here said the FBI sold them, but I never heard about anything like that on the news, so I'm not sure what they did with them.
