well that person is probably LIKASHING(not the real lika just his AKA) he used to bet 200 btc at a time on just-dice. I saw that person bet billions in under a minute some days, good guy he deserves it gave me 1 btc which i lost because i was quite ignorant at the time as a xmas present.

or a big miner, no one will every know the truth haha. i did try to advise him to stop gambling.
