With only $200-$500, you're not ready to invest. Put it in the bank and continue to save as you can.

I would like to know the differences of a ETF and a DSPP. What would be the easiest to invest with little money around $200-500 starting? Also what would be easier to understand for a beginner? Lastly, which would have the higher risk and profitable either long term/ short term? Does an ETF require a broker?
