Hey @haejin, On bittrex BTC already went 6.7k and the volatility is too high.. I think a correction might be due for the next few days, as you have mentioned but the price range I'm not too sure about, but the resumption back to bull market will be eventual but i believe there is time for the altcoin markets to pump in this static time for BTC..
