It very well could be 3 different people that have solved the last few keys.
@Bajula what would you do if you would find the 70-bit key? I tell you what I would do, I would change it to fiat and enjoy the money. But our winner of 70bit key moved the funds to other address and the satoshi are still there from 9 of June and is not the only one.
I still believe that this puzzle has a higher goal. And the goal is not to give 32BTC to the people like you, me or other, some crumbs here and there maybe to make the puzzle legit and to make the enthusiasts still searching for solutions.
Admittedly, I would totally throw it into fiat and pay off my wife's car, that being said there are a few potential reasons the btc hasn't moved. Paranoia, a btc mixer that hasn't drawn on it yet, a few exchanges work in funny ways, hashnest (not sure if they still do this) used to do strange things with btc you sent to it.. (as in you have a spendable balance in hashnest, but the btc is actually just sitting in the address) probably a handful of other possibilities that aren't nefarious. - now THAT being said. I have a tendency to look at people with an anti-shady filter in my rose-colored glasses. (I try to look for ways to NOT see the worst in people) I've been wrong, but less often than you'd think: for the natural skeptic's justification: when I am wrong it's like a physical blow to whatever my "soul" might be.
