Luckily though this very week the first prize of the weekly lottery was won by a guy with 231 million tickets which got 0.34 Bitcoin and the amount you need to buy the 231 million is 0.231 but maybe he got them because he wagered a lot and refs of him wagered a lot too,point is I am always happy when someone with a lot of number of tickets wins the lottery.
I believe it's the very same guy who wagered 500+ BTC, because I haven't seen a 1st prize lottery that big in a long time.
I actually got almost 0.5% of all lottery tickets myself, was a big wager round for me, took about 400k RPs during the promo, so I'm pretty happy, except that I wagered even more before the RP bonus was active lol
All in all, all the wagering was almost zero profit, but the RPs, and the wager bonus, plus cashback, I made 10 mbtc. Very small amount for my wager
