Comment Re:Bitcoin to bypass unfavorable exchange rates? (Score 1) 54

Isn't is equally likely that you will gain or lose value due to volatility?

Doesn't work out well when you need a specific amount of Swiss Francs in the future.

Stocks are similar - when dollar cost averaging into stocks (e.g., buying $100 per week) volatility is your friend, you'll end up with more shares of a volatile stock than a stable one (with same average price) over time. When you need a fixed income out of stocks, you get screwed by volatility for exactly the same reason (the math works out to gains/(volatility^2)). This is why the common wisdom for financial planning is to invest in stocks to start with, but gradually shift into bonds as you near retirement (there are even "target date" mutual funds that work that way).

It's a dancing bear - the point is not how well the bear dances.

The encryption is trivial. The point is that neural nets were able to come up with anything. The impressive part, as I understand it, was that there was no side channel here. Anything Alice and Bob said while developing the encryption - the whole process of agreeing on how it works - was overhead by Eve. That's kind of neat, for some neural nets trying shit at (weighted) random.
