If he only played gambling by taking risks, he would not be able to win a lot of money but would suffer losses.
It's better to try to spread referral links than play gambling because it doesn't cause us to lose money.
By trying to do something like that, he might potentially make money from referral links and not have to gamble.
But it seems like OP is aiming to get $100 daily profit no matter what method it is base on his/her last post.
And I agree with you that if OP would use his/her money to play it would be really risky if he/she is aiming for a regular income.
The best way for OP to achieve his/her goal is by referral program but it would take time and it would be really hard.
