You can't win in gambling without losing because gambling is all about taking risk and losing. If you want to win without losing I think investing is the best thing for you.
Investing is also risky so there is no assurance that you cant lose your money regardless how trusted the company. in gambling, there is no way you can win without losing and its really impossible.
If we choose gambling casino to invest than our chance to make profit is so high in long term, everyone knows this the house always win in the end, but investment in any HYIP or Ponzi is really dangerous and I have no doubt it.
