What would you suggest as a safe and profitable investment?

All these things can be done only if you have the knowledge of the whole system and as far as them being safe goes, no - They are not safe! Among all these or others, I guess Forex is the most secure one. Then again, Its just what I think, I am no expert here of investments... If you are good for betting then there are a few sports betting ways that are safe.

Of course, the safer and the lesser the risk, the lower the yield and rewards. It would really depend on your risk tolerance. If you are risk averse, try going into special deposits and money market funds. Time deposits have gains which are really low so I don't suggest them. If you have a tolerance for risk try investing in mutual funds. Fund managers have the know how and expertise to help you gain money, it's just about trusting them. If you don't trust others then go for stocks, however, these are very volatile securities but very high yielding and rewarding. Gold and silver is a nice investment but of course it is safe but not as rewarding as stock yields. Try to look for other bank products that suit you best. They will assess your risk tolerance and would be able to suggest what investments is appropriate for your personality so do drop by your trusted bank.

Well, if you want top invest your money by online ways, the best way was for your own site.

I would invest in shares via a cheap tracker whilst learning more about researching individual companies. Over time shares have tended to go up by about 10% a yr on average whilst gold has only just kept up with inflation.

you mentioned that you have knowledge about all that stuff so i would advise you to try your habds in shares, mutual funds and FOrex, although among ll three Share market is most risky but mutual funds and forex aren't that much i would say investing in mutual funds is better than Shares. O for Mutual fund investment. You can do it by visiting any banks nearby you they will explain you everything. Mutual funds investment are actually same as Share markt but it is done by some specialists, they take money from you and invest it in different regions where they have cances of growing up. I don't know much about it but will happy Share with you how much i know. Forex is also a less risky investment because international currencies rates not move much, so if you investing in forex it is obvious that you have to invest some big amount to gain some big. It will not double or tripple but it will give some percent of that amount, perent is in single digit only. Try investing in which you have knowledge, where you know you can make it up at worst situations. Also never invest money on loan or money you ave after loosing you will be left with nothing. try investing you extra money which you will not sad after loosing it.
