The only thing that matters is future profits.

Decide on your algorithm now, and come back in a week (.. month, or year) and tell us how much it actually could have made.

It is trivial to find and algorithm have would have traded for immense profits historically. I know if could do much "better" than what the author published above, only by following known fixpoints. But that strategy would not own me even a millibitcoin in the future.

And netiher would the author's. Or...? The proof is in the pudding, as they say.
