Sorry, maybe I'm just tired, but I'm confused by your post.
> 15% of your money in something technically promising but risky isn't really worth the time you'd have to put into the research for it. Put in 50% at the very least. You'll make money if you are right and if you're bad at investing it will be safe enough for you to survive retirement.
Are you talking about investing in one's own venture (where you're looking for high return), or investing for retirement (in a diversified portfolio w/ low-fee ETF's, where an 8%-per-year return is great)?
