Since the price is below 200 daily ema and as you can see in the chart everytime price touches 20 ema it goes down for 20%. if we assume it will repeat again we can expect a 20% downside movement again.
if we assume the hype is over and if just like 11 Dec '17 we go to a bear market after a price spike, we can expect a 6 to 12 month sideway movement wiggling between 19k and 29k.
