Good-Person
Captain Junkie
This kind of business don't suppose to be on this section. Cos it isn't a high risk investment or business idea. It is a profitable business that needs high level of expertise to make dividends. Because lots of service providers are distributing pin to it's recharge card vendors to make recharges and resell to make their own gain. You can partake in this kind of business, if you feel you can do it.
I think that almost each and every kind of business is risky to some extent and when you invest capital, this is something that you must realise. Definitely, there are many people who become vendors of many companies.
