From the article:
>Specifically, every two seconds they predicted the average price movement over the following 10 seconds. If the price movement was higher than a certain threshold, they bought a Bitcoin; if it was lower than the opposite threshold, they sold one; and if it was in-between, they did nothing.
If they are indeed predicting the price at X+10 seconds at second X, they have more than enough time to act on that info without having to do HFT.

Many HFTs hold positions for seconds or minutes, and predict prices out over similar time horizons, but they'll lose their best winners to competitors if they aren't fast and adept at executing.
