OP has clearly mentioned that he does make a profit at gambling sites but that profit is being taken back by the gambling sites. This means that he wins some games and loses some and therefore makes almost no income from gambling.
So my sincere advice to OP is that he should avoid the casino and even if he wants to gamble, do not make targets that he has to earn 100$ daily. Even earning 100$ from trading is not possible. i do not understand why people think that earning money through cryptocurrencies is so easy

Yes, that's right, that's the gambler's mistake because he has a daily profit target that he must achieve. Sometimes he doesn't know that every casino game doesn't always give a win every time, for example, I won $ 20 and to get $ 100, I need another $ 80, to achieve this it will usually drain our money too. , that's why there must be self-satisfaction, don't be judged by a certain amount of money.
I believe that playing with a small profit as long as it's consistent will be even better, you don't have to be $ 100 at least to feel enough with even a little win that will be good too, it's hard to get a $ 100 win every day because we know the dealer won't let you win every day.
