Sorry can't say I know specifics, just that I first heard about crypto because my husband told me he had heard of opportunities in that space. I had never heard of crypto besides Bitcoin and didn't understand. It was two other companies that had a guarantee of double the investment in 90 days...my response was yeah right...uh, no thank you. The word guarantee is what put up red flags for me. I'm all for finding legit coins and seeing even higher returns. Anyways, who the heck knows if they were too good to be true but if something feels off, I agree, at least sleep on it. Legit crypto in general is a tasty target for Ponzis. I posted about that the other day.
