There is a website that gives around that same percentage on investment and it is trusted by alot of people, I'm not sure if it is the same one as yours but I won't reveal the website as you want to pm them directly and gain referrals.
If anyone wants to know the website that I'm using feel free to pm me
The site I talk about has everything on face. Documentation + Contracts. Website owner, you can check the office in Spain
Theses kind of things can easily fake by photoshop , trust me , i did invest much in HYIP and i've been through all. First of all, maybe they really trade and earn some profits to give back to you. But finally if they lose, they will scam you and all gone. Nothing left.
