After Markus Persson sold Minecraft for 2.5 billion dollars in 2014 what has he been doing?

I looked at his twitter account and he just has jokes and funny comments but what else has he been doing with all that money?

No

You think, he is losing sleep or cares

Enjoying all of his money, I'd imagine.

I have played Minecraft. It was enjoyable but it was not deserving of the acclaim it received upon release.
