the TRUST factor is pretty big in my mind ...
as others have posted, one of the things ingrained in dancers from their first time in a club is NEVER trust your money to someone else. Dancers are also usually pretty independent and intelligent and can handle their own investments. In my own case I own a home, a few stocks (my favorite lately is TSGTF - Chinese Beer), a GIC fund, a Swiss bank account denominated in Euros, some gold bars, etc. I also have been trading options lately and doing fairly well with those in light of recent market volatility.
Actually, the investment side of dancer finances is only half of the equation. Our business and tax situation can be so complicated that structuring investments the wrong way can result in major tax consequences, particularly if we work in several different states or have several different "businesses" i.e. webcams and merchandise sales. Business structure and tax planning are every bit as important as choosing good investments.
If you want to help dancers with their investments, we'd be more than happy to have you post some of your ideas right here!
