now we have 17 witness, about 11 witness published price at 0.02, but the mdedian price is still 0.0216, 
because there are almost 13 wintess don't update price over 1 hour
some of them are voted out, so they can't publish price any more
so you'd better use the price published in 1 hour, or exclude the unactive witness's price
