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

Yeah, it's basically how casinos make their money.
They make the gambler think they are in positive, when in reality if you add up everything they are losing money.
Earning money in alt coins is easy for the person that creates the coins out of thin air, the people that pay real money for it are basically losing it all or most of it.
Every single gambler knows that in the long run they are in red yet they keep playing in hopes that they will get that big of a win,it is that that keeps gamblers coming back even when they go bust in a big way by losing a lot of money otherwise they would stop gambling very quickly.No one can make 100 dollars every single day in a casino as this is plain impossible but everybody keeps coming back there to try their luck in a new day and this is what keeps casinos happy as they get money in every day because from 100% of gamblers playing there only 5-10% win something while 90% go bust most of the time.
The only chance someone can make 100 dollars daily is if they play skill games like texas holdem poker or sport betting where 50% of skill is still involved.
