Network marketing is a nice idea. Actually my friends and other residents in our province has known bitcoin through this networking using bitcoins as payment. If not because of this networking schemes bitcoin could not spread in my country very fast. If there will be more networking companies that will use bitcoin as mode of payment then surely bitcoin will be known worldwide.
I agree with you. I have worked for one of the network marketing companies in the past. After 5 years of the company entrance in my country, nearly everyone knows the company and knows something about that company. The use of bitcoin at the networking schemes is a good way for the profit and also for the awareness. Especially technology companies can do that easily.
