I would consider myself a "highroller" if i was playing .5-1BTC, not 16 or 24BTC in a roll...
These bets is just crazy but it's true and that's the best thing here.
Congrats man, really wish to have your luck or 1 of your 300BTC
Someone betting with those amounts have mental issues and will soon be broke and nowhere near a high roller. Lucky this time.
That or he could really be a true gambler. There were crazy stories of highstakes poker players gambling and spewing money outside of poker. One known poker player is Phil Ivey. He'd gamble millions in blackjack, craps, baccarat or anything where he thinks he can gain an edge. So if you think he has mental issues, think again. He could be a
pro.
Yeah except Phil Ivey would not be playing with any types of Bitcoin casinos. One reason is probably due to legislation and him residing in New Jersey I don't think its legal for him to play online with bitcoins.
I saw a documentary about him also, and its really surprising that he won lots of money playing Poker online on FullTilt, most profesional poker players are usually only good at playing in a real casino not online, however he managed to do both which is pretty impressive.
