I have never played online gambling because I think it is totally a waste of time and money.
You never experienced the good and bad side of gambling so if you are still thinking that this is only a waste of time and money, you better stay on where you are and don't ever try it. But again, you'll never experience what we felt.
Online gambling sites will only take your money and will not give your winnings.
They won't give the winnings? wrong on this part, you'll only experience this if you gamble with the wrong casino. Most of the reputable casino's are working perfectly if its about the withdrawals.
Other thing is that 8 hours in a single day for online gambling means that you are losing your health because in online gambling you will have to set in front of your computer which is not good for health.
You lose your time but its up to your lifestyle about on how would you maintain your health.
