I don't think this is a scam. However it does carry a very high level of counter party risk. If anyone loses their principal, the result would be the same if this was a scam, or just a risky investment that didn't pan out.
This is an unsecured loan to someone you have never met. Just like all uia's. Dichalcog3nid3, people might be more comfortable loaning if they understood what your business case was, and how you were obtaining profit to pay them back.
As for me, I will continue supporting you unless I find a reason not to. I do think people should be aware of the risk, especially you. If a problem comes up people will not assume positive intent. Ensure you do not bite off more than you can chew.
