If it makes you happy here is the video from the conference in Frankfurt
https://youtu.be/wCc7nFk3h3w instead of looking for issues you should try and learn a little first and see what a huge investment potential you could be missing out on instead of slandering something with zero proof.
I think you have that backwards by friend. There have been thousands (and thousands) of multi level marketing passive income opps that promised the moon only to walk away with their investors money. Approaching any of them without rational skepticism is foolhardy at best. It isn't on me to prove they're a scam, it's on Jubilee to prove they aren't.
I see Jubilee is a registered business in the British Virgin Islands, you know what, for less than $1K anyone can be registered in the BVI.
What I don't see is any sort of registration for an investment opportunity. In the US they would need SEC registration as well as in each State they market in. If they allow investments from US residents they still would. Is Jubilee registered with any nations investment regulators?
Independent financial audits of Jubilee's business earnings, are these available to investors? If not how do we know they are profitable enough to pay the investors the promised returns? It would be easy for them to repay old investors with new investors funds but that would make them a ponzi scheme. Do we have ANY independent proof that they aren't robbing Peter to pay Paul? If not how can we be sure we wont be Peter?
We all know they are very very many scams out there, we all know we need to be careful with our investments. What proof does Jubilee offer that they aren't (yet another) scam?
