.There is no alternative for money ...
There is now and that is cryptocurrency. But if we are talking about fake money in gambling then I agree with you
these alternative for money will not work
Cryptocurrency works the same way as money so it will have the same effect when use in gambling. But fake money won't have the same result since there is no adrenaline rush if we use it to gamble.
I would highly not recommend to use different apps for the money game - rather save your time and do something productive
If a person's target is entertainment then it is highly advisable to download the apps stated at the OP to save money. But if they wanted to win money then they better use the online Casino to bet.
