What does a Citibank decal on a car have to do with the legitimacy of CMKX? There is nothing inappropriate about the racecar! If Citibank puts a decal on the CMKX certs, then you've got me convinced, but getting your company's name on TV is the goal of any company.
How can you believe that a decal on a car makes a company legitimate or backed for that matter? Ever been to a pro golf tournament? There is usually a board showing all sponsors. Does this mean that each sponsor backs the other sponsors on the board? Or even knows who they are?
If you have to reach this far to legitimize your investment, perhaps you should reconsider what enticed you to buy in the first place?
