You actually took the words out of my mouth. I really don't know why anybody would want to invest all they have into a single investment no matter how lucrative it seems. Thumbs up for this advice!
Spreading of investment is a good idea. But for a newbie investor. It is a suicide to invest on different investment because it requires careful study on each investment and focus investment is much compatible. For me. Focusing in one goal or investment will have a lot of chance to earn profit rather than scattered funds.
Investment is not suited for newbies, without having proper knowledge entering this field is not advisable. Before going into this field first learn how to invest and where to invest and where if you invested how much profit you will get in month/year. Like this lot of research required. Once you get full confidence, then you can risk your money. Till that investing is not good for anyone.
