You can have an online site hustle if you have 1000 dollars and of course I am not going to tell you which one as there are plenty of them,you just have to be careful to do your own research to not fall into scam as also scams online are in huge quantity.If they were talking as gambling with 1000 dollars and considering it as business that is the worse of all the ideas as that money can go as soon as just three days.
Therefore they should stop right away as if they continue their medical health condition will get worse and worse as that is the only way if you keep gambling and considering it as a business no matter what "strategy" you apply to it.
If are just gambler then it is not business because business is an activity that can develop and generate certain amount of profit while gambling is an activity that can spend money.
Moreover, with $1000 won't be able to have any business in gambling and if this is used for gambling capital then what you say is true is that it can run out very quickly with nothing left.
Everyone must be able to really take wise decisions with the money they have, if mistake occurs then the main thing that must be faced is to be willing to lose all the money.
I don't think there are people who consider gambling as business, I also believe they have too high hopes to see what is good and bad.
Not everything in gambling can be considered bad, but if the attitude and approach is wrong first then it is clear that it will only be bad result, they must immediately realize it before everything they have is lost.
