Remember that CITIBANK got fined a few million in Mexico for laundering money, so banks are not inmune from corruption, favorite neese no 2 her husband is the second big wigg at the bolsa de valores in Mexico City.
And Maidof's and piramid investment deals can happen in big banks and investment intitutes any where in Latin America, I tried to read the original article all I got was some dubious subscription add so I was not able to read it, I do not respond to those adds at all.
So be aware of investments that are some times to good to be true, greed can also play into someone investing into bad deals.
So invest your money wiselly, hard come easy go.
