I am surprised this hasn't been spun with clickbait tagline like: Sony invested $150M into Bitcoin. Followed by a few rocket ship emojis.
The hadline makes it seem Sony had so many bitcoins, and they were stolen. No, Sony had cash, it was stolen, and got converted. An equivalent headline might be "US returns $154M in Lamborghinis stolen by Sony employee." and you'd be wondering Why Sony had so many Lamborghinis...
