Developing your own way of gambling is best what will help us to go in this line otherwise copying others might be costly sometimes.For example if i try to copy some big gambler and bet high say $100 and loose it instantly then what will i do at that point because it's far more than what i afford to loose.So play according to yourself and enjoy it within limits.
The thing is that the one whom you are copying must be having higher budget than yourself which is why that person can afford to lose the amount but you can't.
Copy gambling is very risky and must be avoided at all costs. It's also completely useless in luck bases games where since every person has a different luck.
On the other hand, creating you strategy and testing your own luck is more beneficial as it will improve your style of gambling while staying within your budgets.
Its better to not mind other's business and focus on ourselves when we play. Dont compare to other gamblers your budget for gambling. If they can wager high that means they're not just an average gambler, but the risk and luck for everyone are still the same in gambling. We have different fate and anyone can hit a jackpot (even you have a small bet) depending on our luck.
Thats why there's a rule to only gamble what you can afford to lose so incase something went wrong then it wont be hard to accept the situation.
