I think it all depends on individual differences the level of income one posses, some persons gamble with huge amount of money it could probably be what they can let go they stake high to win high while some stake gradually with also the little amount they can let go for me what I do is to pick up 2 to 3 odd and stake with high amount and it has been working for me rather than having somany odd and stake with just little amount and i noticed thats the best way to gamble for me.
If someone is staking with a huge amount and they can afford to lose the money, it's up to them. Some people gamble for fun and yet they spend so much at it because they already have too much money from assets they had, so when they lose to gambling, they can still recover it back. If someone is gambling to make money too, they just have to gamble with the amount they can afford to lose too, because when they stake with money that they should have used to achieve other great thing, they can just end up losing it in gambling. Gambling is not something to put an entire hope on.
