- What does "they're the real deal" mean?
- Two years is not enough to test a strategy like this. 20 years would be better better, but it sounds like they already did that and the strategy fails half the time (hence the 10-year claim)? Does it fail randomly, or did they market a strategy that worked for the first 10 years, then didn't, and now have a new strategy with the same claims?
I'm asking these questions because people usually work hard for their money, and when someone makes (or relays) a claim that they can consistently multiply it better than expected, skepticism and scrutiny is imperative.
