I attended presentation sessions of a few MLM businesses and noticed certain facts applicable for all of them.
First of all they will try to paint a rosy picture about the prospects in their business and monetary gains, but in practice it is very hard to achieve. In all MLM companies the income is in a pyramid structure and the higher you are in the pyramid structure the better are the monetary prospects.
Let me explain this pyramid structure of income with little details. Suppose somebody invites you to join a particular MLM company, you joined and purchased products. Now based on your purchase the person who invited you will get a commission. After sometime you invited another person and she/he joined and purchased products according to requirement. In this case, you are getting a commission as well as the person who invited you to join the business will also get a commission. So, this chain will go on for all the recruits.
In most of the cases the cost of the product is very high and it becomes very difficult to convince the customer if she/he is not much closer to you. Moreover you have to recruit persons as your down lines to get the business going. If you have a good fan following you may try, but in the long run it may become difficult to continue.
