1st one must be a trex wallet?
Yes. If it wasn't we would all be in trouble. I do think the 500K size wallets are the same group or individual. Does anyone know what the premine amount was?
hmm wasn't there a guy who bought 38 btc worth of VDO, i think its a person not bittrex
edit : see page 44
I'm for certain the largest wallet is Bittrex, I used the explorer to follow almost every withdraw (outputs) that have taken place. The guys that own the 500K wallets own 80% of the small ranked wallets between 30-55 top addresses. The guy that owns 38btc worth, if he hasn't sold for profit already probally has most of his coins in smaller wallets that don't show up on richlist rank wallets. You have to look through the hash inputs/outputs to see the real picture. Its very interesting.
