The purpose of the investment. For example, your investment interests may be to earn an income (regular payments such as dividends or interest) or to grow (raising your capital at the maturity of the investment) or to keep your capital safe. This information also relates to your willingness to accept your risk and your inclination to risk.
Before you make any investment, you need to fix your target and learn as much as possible about it. You can't just venture in something that is like a stranger for you, you may lose everythig.
So, be careful what you chose and how will you deal with it because the sock investment is so risky but, if you know how to own it, you win.

The investment is one pf the best ways of making profit in our times. You just have to choose the best company or product in which you will give some money and if that thing is successful or popular or well sold then you will get your part from the profit. The profit is as big as the money you invested in at the beginning.
Now your investment interests should be into the IT domain. The IT domain is growing and nobody can tell the exact time when it will collapse. But, as how the world and the people seems now, I can assure you that it won't collapse soon.
So this is what you gonna do: get some money, find a new and promising IT company (computers, smartphones, devices,... you got that), study the product which it promotes and support their efforts by giving them money.
