Can we make a list of guys that are not anonymous and they have a nice stash like 10000btc+ ? I can only remember of Winklevoss Twins and Tim Draper.
Erik Vorhees sold SatoshiDice for over 120.000 BTC in 2013.
Roger Ver is known as a huge Bitcoin holder as well.
I also could imagine Trace Mayer owning a shitload of coins.
Mark Karpeles
Mircea Popescu (some romanian guy)
There is also a chinese guy (early miner) which name I forgot who shall also own around 100k coins
But what do you expect to do when you know the names? Begging?
