It's all about the risk-reward ratio. If you have a metod that yields 1:3 RR, you may take an annual risk of 1% on capital to earn a annual 3% return. You can scale it up and you can scale it down, you can chose exactly the risk level you are comfortable with.
"If, If, If" If you can sell earthworms in a fishing capital of some country, you can make a killing, spelling out R:R without showing OP is like saying if you have a method that returns 100 to 1, that's the one you want to trade, there is no clear R:R, as there is no concrete formula of getting 3 to 1 unless you taken 10,000 trades.

hmm, i think a div stock oriented strategy looks nice, esp if there's any way to get some tax breaks. see REITs (if u in germany which it sounds like you are)
