A game where you win once today and lose many times what you won the previous day, and yet you continue accepting that it's all part of the game – those are true gamblers who are out and ready to gamble. If you are not a risk taker, you are thoroughly not ready to start gambling. The best way to gamble is to accept that you have lost the money you stake on a game the moment you click to place a bet.
Gambling itself already implies risk. How can you play and not take risks? It's simply impossible. But don't you need to increase the bet to hit the jackpot? You won't be able to win a lot of money if the bet is minimal. For example, spinning slots at the minimum. What will come of it? Total disappointment and nothing more. Still, sometimes you should take a significant risk that can be justified.
Yes, If you don't take risks in gambling, there is no chance of getting the jackpot. Those who take high risks have a higher chance of winning the jackpot. There are some gamblers who can't take high risks but they expect to win big, I think they will have more chance of getting frustrated in gambling. If there is money, then the gambler can take risks after setting a limit. For those who only take gambling as fun, there is no problem even if they don't take risks, but if someone expects to get the jackpot, then he must have the ability to lose the money. If he gambles in this way, if his luck favors him at some point, he can get the jackpot.
