The pitfalls of an Mlm business are fairly obvious, you only get paid commission on the products you sell not the time you put into the business, this means working for free until things get off the ground. One of the things I would like to make people aware of is; some Mlm businesses require you to buy an upfront stock in large quantities to sell on to customers, I would not advise joining an opportunity of this nature as it is bordering pyramid selling.
