I see lot of advertisements offering trading tips in shares, future and options and commodities,etc. Many of them sell such tips for money and quote returns from the past like 100%,200%,etc .
If the sites that offer are confident about their recommendations, then they can very well make use of their own tips to multiply the money they have. There would not be any need for them to sell such tips for such meagre money.
Investors should always follow time tested methods and shouldn't fall to such cheap shortcuts to make money.
A realistic expectation, well understood investment and a patient approach would help any one make money over the long run through equity.
