Success in predicting markets is measured in profit.<p>This research team should start a company that offers a service that allows users to deposit bitcoins, which the company then invests according to their alleged predictions, and then pay interest on deposits, and keep a part of the profit for themselves.<p>Doubling the initial investment one time is one thing, but this hypothetical company being able to double its investment every 50 days for years is something else. I doubt they can. A doubling every 50 days is x160 every year.<p>I think claims of being able to predict market prices should be met with great skepticism. Especially prices of easily traded commodities, including bitcoins.<p>The only proper measure of an ability to predict market prices is profit, because profit also measures the extent of the predictions: how much can you move the market (by trading according to your predictions) until you can no longer predict what will happen? Obviously, there's a limit. No one can extract unlimited profit from any market. So there definitely <i>is</i> a limit to how much you can earn from your algorithm. If you can earn 10% p.a. on an investment of maximum $5000, your algorithm isn't really worth much. If you can earn 1000% p.a. on an investment of up to $100M, your algorithm is <i>great</i>. But without knowing these figures we really only have a claim, seemingly a claim of them being able to make <i>a lot</i> of money, but choosing not to do so.
