Damn, New York is outrageously expensive...

In stories like this you always have to ask how many bitcoins did the person own in first place that they could offer up 50k from that stash this easily. I'd say we might have had a big ass whale with a lot more than just 50k bitcoins.

Additionally we can not really blame the seller either because the offer was $1 million below the ask price. In other words if they really wanted to invest in bitcoin they could have sold their property for $14 million fiat and then bought 3846 more bitcoins with that fiat which is an additional $0.38 billion profit ($5.38 billion total).

Also lets not forget that 2015 was mostly a bear market year and filled with lots of FUD. To the point when even by the end of the year one of bitcoin core developers, Mike Hearn spread a FUD calling bitcoin "dead"! I wouldn't really blame anybody who didn't want to touch bitcoin back then.
P.S. It is interesting to look back at all the FUD some of us have endured all these years and still kept HODLing...
