A 5 yr multiple entry visa is given to people with sound portfolio and satisfactory interview. It is nothing new, but most people don't get it, as we have a tendency to make fake documents and think that it won't get checked.
I've seen people borrowing money to show a bank statement of millions but when a simple question about income tax return is asked they try to fool the consulate people resulting in rejection of visa or getting black listed. Be straight forward and truthful and you are likely to get max limit visa
