Well theres nothing impossible. Maybe that would be happen but I think it needs patient so that you can wait with a vibe. $20,000 is a big amount but hopefully bitcoin could raise hugher than that.

Anything is possible with bitcoin.One day the price is very high and the very next day the price will fall.As we can see the graph of previous months ,this situation can be possible.Falling down to 4000 dollar is very common.But their is nothing to panic.Bitcoin will recover and soon it will reach a great height in coming years.

Hopefully it will not drop to 4000$ although with so many predictions still price are unpredictable. Bitcoin will likely to recover as always we cannot tell when. At this present time let us hope btc can gives a good show it’s prices.

At the moment we can see that Bitcoin price has droped few hundred dollars so probably there are some who predict it will not stop there but go all the way down to 4000$.
It's not impossibe scenario having in mind how unpredictable Bitcoin can be and how easily price can change but to my opinion this will not happen. In fact I expect slight price growth by the end of the year.
