is this scam or no ?
You don't need to ask!
Of course its a scam and a ponzi, what else?
I'm old enough to have gone through the first HYIP craze. It came about when the first e-currencies came about.
Currencies like e-gold and e-bullion made it easy to transfer very little amounts at very little cost.
This provided the ground on which hundreds of ponzi schemes developed. Of course not a single survived even though some of them grew so big as to be mutli-million dollar enterprises.
In the end, not even the e-currencies survived
Now with the new crypto currencies the ground is set for the new wave of HYIP (High Yield Investment Programs).
No matter how well they try to hide that they are ponzi, no matter how plausible their explanations (we day trade options, we are world's smartest traders, we are buying life insurance, we have a secret robot...) the bottom line is simple:
GREED is a powerful force that makes the most knowledgeable investor into an idiot. "What if this is for real" can easily kill the voice of logic in your head.
Of course, a lot of people FULLY realize that they are entering a ponzi. And they take the risk because they believe it will stay alive for at least some time to enable them to get their investment back plus some profit.
You see, greed works both ways: the ponzi builders are also greedy, so they will try to keep up payments as long as they can before they decide to disappear with your money.
If you feel that you are drawn into this, enter with the FULL REALIZATION that you are entering a ponzi hoping to get out of the pyramid while it is still sucking in suckers.
And of course never ever pay them money you can't afford to lose.
