Always look at the volume on Stamp before you sell.  In this case there was about 20K btc volume on a 4 hour candle which had eclipsed anything that had happened in the past 2 months. We were also on a fib line at $560 and the trendline that everyone is following is at $530, as well as various EMA lines on the 1D, 3D and 1W charts. The 'news' behind the selloff was weak as well - Someone is going to sell some coins (at auction. not even on an exchange)- so what? What does this have to do with the fundamentals of Bitcoin?
