The way pyramid schemes are structured requires them to constantly recruit new people into the scheme. But this is unsustainable because at a certain point you run out of new recruits either because 1) you can no longer find anyone interested in joining, or 2) everyone on earth has become a member of the pyramid scheme. When you run out of new recruits, the pyramid collapses, leaving those at the bottom with a loss.
Unlike many MLMs that sell products directly to consumers, Digital Altitude sells a business system to entrepreneurs in the form of courses and methods that teach them to effectively market their own companies. While many of the packages can cost thousands of dollars, Digital Altitude offers a $1 trial, making the risk to try its product very low for the consumer.
(Update: In April of 2017 there was an article posted about this company, so as of May 2017 it is unsure if this company has gone under.) First off, to sign up and become an affiliate of the company you might do a double or triple or quadruple take at the startup cost (which is almost 4 figures). However, you do get to truly set up your own business, because you can set the price on all the products you sell. If you have that business talent to make consumers buy the products (which are legit btw) you can certainly make that start-up cost back in no time. This company has also been achieving some high praise by being the recipient of many awards (including a growth award from the Direct Selling Association).
Marketing is part industry-driven and part creative thinking. In the case of network marketing, it is also about finding salespeople with charisma. When you hire people who are excited about your business and product, they will share that enthusiasm with others. An enthusiastic sales force leads to more sales, but also to more recruits into your marketing network.
If you insist on trying one of these MLM offers, the least you can do is look for proper business registration with BBB, toll free number, and proper address (no Post Office box). Also, you will need lots of family and friends to make it work. As a final step, check the MLM materials for one or more of these "red flags" that are associated with the worst of the offerings:
