Is this only to me looks like a Ponzi scheme?
Probably yeah, lol

To some of us is even worse, a Ponzi scheme comes with a promise of gaining x% in a month or week or something, this, let's call it scheme only promises to take a 10-15% chunk of your money for delivering you
shitcoins altcoins. I'm trying hard to see what the OP claims to be "mutual gains" but I can't see any trace of it, unless he plans to disclose what those miraculous bonuses are and how are they delivered.
I mean if you have $100, how you can have $120 if you don't do anything (except to send money to you). I've been looking for such an opportunity for my whole life and I haven't found it.
See, that's the problem, this service doesn't work like that. You have 100$ in
BTC and then you have 80$ in altcoins.

To be honest at this point it's even hard to call it an outright scam, the user is telling you right from the strat he will exchange your bitcoins at 80% of it's value in altcoins, taking a commission for this, so, god....I don't know if it's cause but this last heatwave heating some parts of the globe but people have started to come with some pretty silly ideas in the last days in services and projects.
100$ btc will make you 5% weekly x 4 = 20% so 20% month 12x 20= 240% Roi in one year.
And it will be payed weekly with 5% with 2 different altcoins.
Simple questions:
How do you plan on turning 100$ in more than 240$ , in order for you to also get a profit ?
If you already have a method, why don't you do that with your own money and get a ROI of at least 240% without paying strangers that interest?
Im going to trade and use it some of the funds as leverage.
But okay what is the good idea it can make money for me and my customers.
