I think they are just curious about bitcoin and the amount they invest like other said is just a small amount that i think its under testing if they can make a large amount of profit since they already bought 2 bitcoin more or less they can make a large profit if the price of bitcoin will increase more after this august  if they discover that there is a good profit in holding bitcoin expect that they can invest more in bitcoin that can also affected the price to go more high or it can be worst result because he can control the value of bitcoin and gaining this man can make more profit.. just lets hope that it can help to increase the value of bitcoin or else he is trying to manipulate the price of bitcoin.
