分析 | Coindesk：熊市或將繼續持續:據Coindesk分析，三個月來BTC首次低于關鍵的長期支撐位4000美元，BTC已經跌至21個月EMA支撐位下方，熊市將繼續數月的可能性進一步增強。跌至EMA支撐位下方標志意味著雖然在短期內可以看到放量反彈，但目前已經排除了回升至21個月EMA以上水平的可能性。在4小時圖上，BTC突破下跌通道，100EMA低于200EMA，50EMA低于100EMA，這是典型的看跌指標。BTC可能在接下來的24小時內試探近日高點4500美元，驗證4小時圖相對強弱指數（RSI）的看漲背離。[2018/11/27]

Coindesk行情分析：BTC可能會下降至8865美元:Coindesk今日發表BTC走勢分析文章，文章指出，昨日（07日）BTC收盤價低于10日均線，這預示短期牛市失效，周末未能突破關鍵逆向頭肩頂頸線阻力。BTC在今日早些時候嘗試重新獲得10日均線失敗，5日均線看跌。因此預測，BTC可能會下降至8865美元（熊市標志）；收盤價低于100日均線8897美元將確認短期看漲趨勢變化，并可能進一步下跌至7787美元（61.8％斐波拉契回撤位從6425美元至9990美元）；另一方面，如果價格高于9678美元，則會上調至10000美元，只有每日收盤在10000美元以上才能恢復看漲前景。[2018/5/8]
