I play a lot of online Casinos, the most I have ever been able to hit since bitcoin reached over 5k was around 0.26 Btc. Don't get me wrong that is pretty nice But Alot of the Casinos I play Have 2, 3, 4 up to 10 btc jackpots, I seen one for 13!!!! has anyone ever hit any jackpots over 3 Btc since Btc, has reached it's all time high??? I still hit .1 Btc occasionally but never have I or anyone I know ever hit any majors?
I believe these payouts were alot more possible back in 2012 and 2013, in the last 2 years has anyone Hit over 3 BTC?

No, I haven't hit any jackpot as of yet in online games. but I have won a lot of mini/major jackpot in landbased casino. You are one lucky guy if you hit 3 bitcoin jackpot during that all-time-high in December. Yeah I agree back then casino's are offering more bitcoin because obviously the price back then is so cheap and more players can spend a lot of their bitcoins trying to hit that big jackpot.
