In last week's article on token holder distribution, 
Turns out that big holder is Yunbi. Surprisingly, this top holder's amounts didn't change in the last week, but it still skews my impressions from last week.
Here's the next question I have: is this unusual? 36% of all tokens is a huge amount for one exchange. Or is it?
Let's look at Golem, because it has been around about as long as First Blood has. Golem has remained steady with the top 100 holders owning 78% of GNT. The top holder has 17.5% of GNT. Let's take a look at the account and see if we can determine if it's an exchange.
This account holds only Golem (Neverdie has been passing out free tokens so we'll ignore them), all from the Poloniex-GNT account. Either it's a whale who owns $85 million in GNT, or it's a cold wallet owned by Poloniex. I'm not sure if there is a way to see if Poloniex owns that much GNT, but if you know, please mention it in the comments.
As for other tokens, Bittrex is the largest holder of SWT, RLC and ANT, owning 25%, 15%, and 17% respectively. They also top the Trustcoin holders list at 23% and are in the top five for many tokens. To answer my question above, yes 36% is a massive amount of tokens for one exchange.
Finally, what do we do with this data? At this time, I don't really know-I do think information can be gleaned by following token movements closely and looking for correlations with price, but I lack the programming and data science chops to do it. Is it a problem that there is a ton of First Blood tokens available through Yunbi? Consider this article a starting point for the curious and if you do know a way to make use of this knowledge, I'd love to see it in the comments!
