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.
No. We look at everything in dollar terms. When the lottery was 0.6, BTC was much lower. So the wagering volume was higher in BTC terms but lower in dollar terms.
Nothing has been changed to offset the Lambo.
