That's assuming that Doog doesn't own a healthy share of the roll himself, which I would imagine he probably does. Still, 626 BTC is nothing to shake a stick at...
I'm not complaining about the commission I get. But it's nowhere near 626 BTC. The commission was 1% at the start, then 5%, and has only been 10% for the last 3 weekly commission runs (I think), so the total commission is around 350 BTC so far.
And of course I'll invest in whatever protection we need to stay up. I believe PrimeDice went with CloudFlare, but it didn't seem to stop them being down for quite a long time.
