Bruce Lee said "I'm not afraid of a man who knows 10,000 different strikes, I'm afraid of a man who has done one type of strike 10,000 times."
And I agree with him, because these words speak of mastery in a narrow direction. It's better to be able to do one thing, but to do it perfectly, that's why I only play the same character in computer games, that's why I prefer the same type of gambling. After all, long practice leads to perfection.
But if it was on football betting would you continue to pick the same team?
Because every player's performance will be different and if you meet a strong opponent then the chances of winning will be smaller, yes but maybe this will be difficult if it is on a sports bet.
But in the types of gambling games such as Slots, crash games, Candy Crush and the like, it may be possible to just focus on one game and find out how the game pattern is rather than moving on to another game without good knowledge and not knowing the pattern.
