The reality is that in gambling, the odds are often not on your side, and unless you have exceptional skill, strategy, or luck, the expected return is almost always negative over time. For most people, it is more likely to lose money than to consistently make money.
In fact, and some exceptional strategies will not help on the distance to stay in the plus, if it is, of course, legal strategies and they do not contradict the rules of online casinos. Otherwise, the account on the platform simply blocked without payment of funds that were on the balance at the time of blocking. Luck may allow you to win big once, but the chances of this is frankly not great and this must be taken into account, so that then do not tear your hair out of your head from unexpected losses.
It is true for casino games - games with random result. In sport betting you can get good result if you good at maths, can search information, make high quality analyze, and can play without emotions 24 hours per day.
I can`t say that it is easy, but strategy, risk management and money management give you an opportunity to get profit regularly.
PS. And you need to have some tricks, to struggle with casino restrictions like bet limits and ban of the account.
