Hi, I've recently started researching and planning to do some investment for some spare cash that I have. I came across POSB's Blue Chip Invest-Saver and OCBC Blue Chip Investment Plan, however, as I'm totally new to investments I have quite some question that I need to clarify with experienced experts over here 
1. How does, say POSB's Invest-Saver work? It says that I just need to contribute at least $100 monthly to invest. So does it mean that I just setup my account and contribute $100 every month? Or do I need to choose which blue-chip I want to specifically invest in?
2. How does blue-chip investment return? I know briefly that they pay dividends. But, when? Annually? And does the dividend automatically gets credited into my POSB account, if I sign up for POSB's Invest-Saver?
3. How does the risks work out? Say if I'm on POSB's Invest-Saver for $100 monthly, after 2 years, if say some thing bad happen to some company or the economy, do I lose 100% of the money from the investment? Or how does it work, can anyone show me an example scenario?
4. Is this kind of investment plan really worth it? Or am I better off going to fixed deposits that are offering 1% pa?
