Yes, but he has been there for much longer and he has miners for like everything that is mineable!
But you're right... insane too

Anyway. If you calculate, 2% is about $300 a year per rig (at today's rate, so probably much more).
I let you decide if it is too much...

And then, you have pool fee, transactions fee, trading fees, withdrawal fee, income taxes...
EDIT: I forgot electricity! that's about 20% for me
Basically, you guys are mining for others! I'm just saying...
