There are questions by many whether this is legal or not. That is almost like asking if concrete is legal. It really depends on how it is used. The matrix system itself is not illegal, unless it is used to perpetuate a fraud or a transaction or exchange of money without any substantial product or consideration for the money spent.
The 2X2 is limited in its width, but is still based on a pyramid with three levels. Level one has 1 person, level two has 2 people and level three has 4 people for a total of 6. A pyramid is not illegal in itself unless it is a pyramid scheme designed to separate people from their money and not deliver any goods or services in exchange.
If a company or individual is selling a product and uses a matrix system as a means of measurement then it certainly is not illegal or fraudulent. If the person parting with funds receives a tangible good or service for their money regardless if there are other considerations or possible bonuses for doing so, then that transaction is legitimate.
There are many products being marketed with a matrix system. Usually you fill up a matrix and move up to another level, which measures your performance and entitles you to move up to the next level, which has greater rewards for filling it.
You most certainly should do your due diligence to check out any program before you become involved with it, but don't let names, titles or fears rob you from benefiting from these legitimate programs.
As long as there is immediate transfer of goods or services and not just a promise of hot air, you are good to go. Then there is the question of the main product the system is marketing. Is it a good product? Is there a great need or market for the product? Is it something you could see yourself being involved in with pride?
The biggest question of all is, will you be left on your own after you give up the money? There are many great programs around, but even a great program, great marketing plan and exceptional product does you no good if you can't sell.
Oh yes, someone has to make contact, and make sales. There are systems now springing up designed to answer this difficulty. Some systems now offer to do the selling for you. Now isn't that nice. You get leads and let someone more equipped on the team do the talking.
I know that most of us fit into that category. Who wouldn't like to have a sales force built into their new business venture?
No doubt there are opportunities popping up and you have to be careful to choose the right one for yourself. I am involved in a few of these myself, so I have had to make many of these choices.
Do your homework. Check everything. Check it again. Make sure of the people involved. Take your time. If they want your money before you get much information, run for the exit.
Any legitimate company will be willing to give you most any information you need to make a decision. If not bid them goodbye. There are some great opportunities to make some real residual income. Just make sure you do your homework before you take the critical step.
But don't become paralyzed with fear to the point you can't be objective or you might as well unplug your computer.
