Understood, and thanks for your feedback!
Some more details. This is my most risky investment approach, by design. I only put in money that I'm sure I won't need for at least another ten years. Not that it wouldn't really badly suck, at least psychologically, if I'd loose all that money (I'm not rich or anything), but I don't need it to "survive".
"Don't need" means that it is the money that remains after all my expenses, and after keeping my emergency fund in good shape (which is currently good for at least 6 months of emergency).
Also, this is not my retirement portfolio. It's a bet to multiply money I can risk.
For actual "at least I'm not going to end up poor" retirement stuff, I'm paying into the German state pension, "Riester" and other non-state pension products, and by holding real estate.
