Sorry for double-post, but this is actually a new one:

I just noticed the odds between the bonds you proposed will be absurd. The 50% interest loss is enormous. The people believing BS&T will yield 7% for a year would get a factor 33 out of their money or something, remember? With half of that accumulating, it's only 6 or so.

I would have to do 27:1.

It doesn't work. It just all goes haywire on these time-scales. That's just the thing, nothing ever works if you assume an exponential money-making machine.
