Why is it unfair that people upvote Haejin? He provides value to us all here. On just my last trade, I was able to gain a full bitcoin by knowing when to sell and when to buy back. That is just one trade. I vote him up because that is the LEAST that I can do to repay him. How is this unfair to others? Sounds like he is being penalized for being successful by a jealous person who provides no value...
