If you want to know what is Karpeles doing I suggest to follow his Twitter:
https://twitter.com/magicaltuxAfter reading some tweets I gotta say he is doing great.
I'm surprised he has twitter & puts stuff about his life on there etc. A lot of people lost a lot of
BTC on MtGox so there will be a lot of anger & ill feeling towards him. I would have thought it'd be better for him to keep a low profile for his own safety, it'd also show those burnt by MtGox a bit of respect.
I wasn't hurt by MtGox but I can imagine those who were being really pissed off seeing him joking about & enjoying life on twitter.
