I take the point that at this particular moment, 3 updates on the TA of BTC a day don’t really show much – most of us are waiting to see what the market is going to do. But look, if the guy wants to post about BTC and 10k+ people want to read a single post then it’s just simple supply and demand and as such I don’t think it should be considered on a par with spam. I’d imagine that there are countless posts on steemit that don’t hold any interest to you – why single out @haejin for special attention? Is it because he is making money? Would you turn down the opportunity to do the same? As you’ve already stated you could ignore the posts or just mute him.
Good luck with your upcoming trades
