I noticed it days ago, but have no idea who's that.

It's Deepbit.

please excuse my ignorance but how do you find this information from this:1VayNert3x1KzbpzMGt2qdqrAThiRovi8

Its an amazing book! I recommend reading it!


Address: 1VayNert3x1KzbpzMGt2qdqrAThiRovi8
Name: Gary Vaynerchuck

It was a joke lol, but a good guess if I may so so myself  

Of course I do. Only ~daily amount of coins is kept online.
Those enormous thousands of BTC are shown because the change is pumped via this address many, many times and it's not related to real sum.

As you may remember, I was among the first miners to support sendmany and included your first transactions in my blocks :)
Generation of my own sendmany TX is coming soon, since I can't remember why I decided not to use them earlier.

Of course I know that, those 800k don't worry me. However I mixed that 50k daily volume and I thought this address is keeping 50k BTC. Now I see it's only around 800 BTC, which is of course fine (I'm keeping similar balance).

DeepBit,

Out of curiosity is 1VayNert a vanity address of just another randomly generated address? If vanity does it have any special meaning?
