Currently about 10%, but considering to rise it to 25%. Watching my money on a bank account and knowing it is used by some other guys to earn sweet money is just disturbing 

Not sure if that's the guy you are talkig about, but I've read a story about a russian dude that was using the servers at work back at 2010-2011.
After a while he had about 1000 bitcoins. And there was a girl that he liked, so he decided to give her a laptop. Bitcoin/USD exchage rate was 1 to 1, so he sold all his coins and bought a laptop for the girl. In couple of months the bitcoin skyrockted to 1k USD.
