This is short-term trading. "Every two seconds they predicted the average price movement (on OKcoin) 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." I don't see them allowing for commissions and fees.
OKcoin, at peak, had a trading volume so high that it's generally considered to be fake - the exchange operators manipulating the price. What this group at MIT may have done is reverse-engineered the fake trade generation algorithm.
