No one is "smart" in gambling, eventhough you are mastered on math. It's all only pure because of his luck, you have read what he said, he lost around 50 bitcoin before he can recovered and won another 100 bitcoin. It was also because he has huge bankroll to deposit again after he loss. There is no techniques too to learn from him
