I think he meant he lost 543 BTC.
Think for the positive side, if you had 500+ btc to lose, you already are better than most of us
absolutely yes he is lost 500+ btc according to op's expression by posting like this.
yeah he is better before lost his 543, now we dont know what he would do, just dont try to recover your past lost.
i will never stop remind people around here to stay away from discontent, trying to get back on positive balance.
its almost impossible with the situation you are in a mess.
