I doubt freebitcoin got enough advertisement out of this.
We think it has been worthwhile. We got a lot of coverage on the crypto news sites and a healthy increase in volume.
Healthy increase in volume, but lower lottery prize, ignore the period that the first prize skyrocket to 1.8-2.0btc (mass multi accounts bot), it's prize now is lesser than 0.5 BTC (which was before that event is 0.5 -> 0.6 btc) but the wager volume right now is much more than before so either it's not really healthy or the prizes have been offset for weeks to pay the Lambo.
