Big drop means big upcoming ricing. BTC will be strong and will be rocketing faster than ever after this panic situation. In my opinion this is a best time to go shopping. BTC will not drop below 5000$ I will start stabilizing and then it will start rocketing to the 30000$ limit in March.
I think there is 0 chance of that. In fact I don't think we will see 20k again for a looong time. People have been burned hard and it will take a lot of time for the enthusiasm to come back.
Be happy with 10k end the end of the year, because there is the other way darker scenario where the economic crisis has just started (see the dow during the last week), in which case I expect bitcoin to go under 1000 and stay there for a few years.
I'd say there is 50-50 chance on the crisis scenario. And if it doesn't happen now it will in 2019, most definitely.
