sigizzang thought it was not bad to selfvote his comment himself first.
But one of KR users told him that he listed on foreigner's selfvote report, and then he also told him about why selfvote is not good for steem.
He thought he invested to steem, and price rise of steem will much more better than getting reward from selfvoting. So he stopped selfvoting. That's all, and good conclusion.

Sorry for bad EN writting XD
