Micro-investing: How to effectively invest frequent small amounts of money in equities? 
Compound interest is your friend. For such a low amount of cash, just pop it into savings accounts or deposits. When you reach about 1.500€ buy one very defensive stock that pays high dividends. With deposits, you don't risk anything, with one stock, you can lose 100% of the investment. That's why it's important to buy defensive stock (food, pharma, ...). Every time you hit 1.500€ after, buy another stock until you have about 10 different stock in different sectors, in different countries. Then buy more stock of the ones you have in portfolio. You're own strategy is pretty good also.
