if any entity grows expotentially, there is something wrong in that, that is the fundamental truth, So getting 50% returns in 1 month is being greedy, invest long term and companies that have a good track record. Stay away from banks for now, because the credit crunch here in US will hot india any time now, real estates will lose value and there will be job cuts. So plan based on that. People who make money always think abt the future. investors who invest seeing growth dont make a lot of money, if you can forsee growth then u tend to make good money
