Earning with gambling is depends on your luck factor, there is no fixed income you can tell. Some day you can win thousands of USD, another day nothing or loss everyhting you bet it all depends on your luck.
That is true about the amount you can earn with gambling, no matter how long you are a gambler or you have a lot of experience. But if you are not lucky at all then you are going to lose. Unlike those newbies that have a very lucky aura they can earn as many as they can base upon to their aim on how long they are going to gamble.
But with some experience they know what thing that you should do in order to win although if you are no luck. But mostly in gambling no matter what you do you will always need luck to win more even newbie can hit some huge winning though because of some of their luck
Well yeah for those experienced ones there are going to do that and they have an alternative if luck is not with them. And it is going to be just an easy way for them since they are not depending on luck so they can possibly earn bigger amount of money with gambling. But I think setting a range of $20 a day is very possible at all.
It is possible if you have the means to do it, bankroll is very important if you are in gambling who's main purpose is to make money. And surely you will need more than $20 as you bankroll to make at least $20 a day. May around $1,000 to $2,000 should be the bankroll and that is possible to make money.
I know there are people who are earning big amount with gambling especially those people that are main source of their income is gambling.
That is there minimum capital $1,000 at all. Just like my uncle, he is able to make $25,000 monthly with physical casino's.
But still he is not giving me some of its portion.
