That said the TOP 5 rich list for addresses gives

but the TOP 5 rich list for guesstimated wallets gives
499678 XdWdQXiC8...
144327 XgV8FpC6R...
120009 XtrmiNg6bg...
104409 Xnn3Wnd6...

From the look of it, XdWdQXiC8 is the wallet of an exchange (haven't bothered to lookup which, but if you find your withdrawal or deposit address in there, you'll know which it is). Also XtrmiNg6bg may have a second address with more than 1386 DRK in it.
Anyway, have a look at your address(es), and let me know if it's complete bull or if there is some shred of correctness to the guesstimations

499678 XdWdQXiC8...This is Cryptsy. I'm 100% sure other several hundred thousands are spread at Poloniex, Mintpal etc.
Seems to me like the distribution is quite good for a young coin and getting better day by day as trading continues.
I personally know quite a few people outside the bitcointalk who picked 1-3K.
