The same applies to every gambling service.
A ponzi isn't gambling, it is fraud and theft.
But there is need for such gambling services, and we see nothing wrong in it.
The first part of that sentence is just bullshit as there are more than enough legitimate and fair gamlbing, gaming and investment services people can avail themselves of and, for that matter, you could actually set up and run yourself. There is no justification for what you are doing. The second part of that sentence is already assumed even though there is no justification for what you are doing.
Warning: You are in the Gambling section. You are likely to eventually lose any money that you gamble/"invest". Additionally, moderators do not remove likely scams. You must use your own brain: caveat emptor. Do not gamble more than you can afford to lose.
This warn is enough for me.
