The number one rule when you come across such juice earning opportunities is "if it's too good to be true, then it's probably a scam". This will save your hard-earned money from getting scammed every other time.
I am glad that you first consulted the community. Please encourage your friends to do the same thing if they are not sure about something. We learn something new every day.
Gives me joy that people are being saved from being victimized by these scummy investment schemes, that's been my mantra ever since I've first heard it in the 6th grade and understood what it meant, kind of reminds of too of that part of the Stairway to Heaven lyrics about all that glitters isn't gold but I digress, such a good thing that there's stuff like this happening once in a while in this board with all the negativity inducing topics here that involves scams, it's refreshing to the eyes to see positive effects of being a member of this forum.
I hope that more people in the future will be like OP, report their findings after consulting here or asking questions.
