Notice the double top which has formed on the chart; with a lower second top indicating buyer exhaustion. Also notice the candle stick with a long wick to the down side also indicating a potential reversal. There is the potential for this thing to drop around 40% (Its had one hell of a run!). It might over shoot on the downside past that point if the selling is violent enough.
THIS IS NOT FINANCIAL ADVISE, ONLY ENTER AN INVESTMENT POSITION AT YOU OWN RISK; CRYPTO IS VOLATILE.
