I don't see that possibility to be honest
I think sub $400 coins are probably gone 4ever
A lot of people will see News like this :

I predict they will either hold what they have and maybe even buy more.......
Don't forget we are talking about Bitcoin. I believe people who were buying in the beginning of December 2013 at $1000+ prices were also saying Bitcoin would never be sub-$1000, and then we had an 18 month bear looking for the bottom at almost ten times lower prices. So I would be really really careful with saying that we won't ever again see sub-$400.
