I think that is way too much unless your monthly income is $10k+.
You shouldn't allocate more than 5% of your income to gambling. You should treat it as an expense because you are mathematically guaranteed to lose it all given that you play with the funds for long enough.
Would you spend $200 a month on movie tickets?
Probably not.
Have the right mindset.
Based on your monthly income, you can inverse your on gambling. Actually investment in gambling will be made without any contradiction and investigation. So it will purely based on your luck. With a luck, you need to be patience to get a decent amount as your profit all the time.
Isn't it also a lot about what's going on in the online gambling market? I prefer to place some bets when there are games that I am really excited about, especially big clashes between the huge teams. Or during the final 8 weeks in the Champions League season and so on. It is not so much about a monthly budget for me.
