That's some huge winnings and little loses what a luck im even afraid to bet those big amounts because the tide of the game always change and it ends for me as a loss.
I guess i should follow your strategy and stick only to a sport i know very well and familiar with.
He has a huge bank roll that's why he can bet that huge amount on a single bet. I believe he has a lot of BTC/ETH on his personal wallet based on how the way he bet. Because I have a small bank roll or low baller bettor then I will not risk that huge money on a single bet even though the odds was good. I hope that OP already cashout and don't be greedy because he might lose it all if he continue to bet like the last bet he do on his screen.
Overall, congratulations to the whooping profit you got there. I'm also using sportsbet as my bookie and they are a good game provider so far with fast 24/7 costumer support available.
