thanks in advance
You might start with this lengthy list of how not to invest.
Don't bother, that post is a complete lie designed to attack MPEX's competitors. It basically says that anything that didn't list on MPEX and happened to have failed was an intentional scam. They even list businesses that are still in operation as scams, for example, DMC. There's even a section on me for example, which would take a five paragraph essay to correct all the lies and inaccuracies. Just ignore him.
