3 years ago, 30k BTC was easily a sum that could be earned by an mediocre SR drug dealer.

It's all an exciting world of conspiracies for the average bitcoiner. All the drops surely have to be apart of some bigger scheme, that probably involves key power players of global magnitude.
This is all exciting and fun!
It would be boring to just admit that the big majority of bitcoins are held by unknown people with unknown intentions. Because you would have to remember, that only a small fraction has been publicly claimed, with also stating the owners intentions.
