In any case to have 19 million tickets plus a ton of lambo tickets plus countless reward points, I am sure even if he lost 5 bitcoins, he got more in return thanks to them than what other places with 1% house edge offers up.
Don't forget, if he wagered 100+ Bitcoins, then he has a bonus amount of about 1 BTC, and during RP bonus he can have up to 1 BTC as a reward. So he theoretically loses 3 BTC. Still, a bad decision to play for 0.19 btc since it's not guaranteed but maybe he is trying to also win more Golden Tickets for that 20 BTC prize coming soon.
