hi, this question is not simple as that, there are no good investments or bad investments- only time will tell. the question is whether you're a risk taker or someone who likes to feel safe and don't want to risk his money for a big profit.
investing in third world countries is a dangerous investment, cause you might lose of your money (political situation, bad economic...), but you can earn a lot of money as well (if the country's economic will improve).
you can check investments in India, Cuba, Thailand...
