I find it hard to believe that their results are provable,

maybe they are just trying to justify their funding. Then again it could be true...........
On a serious note, I think this is probably very close to the mark, I know someone who was very smart with his money all his life and then at age 60, after the loss of his wife, fell victim to such a scam. Totally out of character for him and nothing his friends said made a scrap of difference. House and retirement assets gone in a year !!! Very sad.
