judging by the HR bets , he also had a very lucky streak and managed to make a decent profit in addition to the prize
a good gambler knows his limits , knows when to stop and doesn't act irrationally or chase losses
treat each session as a new one and do not forget - dice or any other game of chance doesn't have memory
if it gave you 10 reds in a row it doesn't mean that it is beyond possible to get another 10 reds , many players do not understand it and this is why online casinos make good money
For example, if I gambled 10 bitcoins and still not in negative and even made some profits, I wouldn't stop and would continue to gamble until I am either comfortably at the first spot or I am starting to make a loss, at break even point I would stop and just take the reward prize and be happy with it while having gambled so much for entertainment as well, if I don't end up at zero and I am still in profit when I reach the first place then I may continue even longer until the game stops to make sure nobody passes me in the last seconds.
