Relying on gambling as source of financial need is very bad idea because you might suffer more losses than getting extra money for your financial needs. It’s better to save the money instead of placing it on gambling.
I always have a target profit which is x2 of my bankroll. No matter what is my bankroll. Potential profit is least of your concern in gambling since you might be prioritizing stop loss when playing since there’s a high chance of losing than winning.
Indeed.
Having gambling as your main source of income is really a bad move because you might end up losing more instead of what you will gain because of the risks that comes along with it. Gambling is a risky income generator if you plan to make it one. You shouldn't even consider it to begin with because gambling is more fun and could give you less stress if you just do it for fun and not for profit.
But if a person really insists to make it as an sideline, then one must also prepare for the possible risks of drawbacks such as losses and being dependent on it with prolonged gambling habit or routine. Though for me, it's still best to have a stable source of income such as regular day job.
