I guess we will see everything fall and bitcoin rise 
I dont think it will drop below 400 in the next 8 months.
I would not sell everything right now because the value of the Bitcoin at the moment is pretty low so I think that it is way better if you wait it out. I dont think it will drop below 400 in the next 8 months.If you wait for some time then the chance of you earning more money will get bigger.
Exactly, this is not the right time to sell, as if you sell now then profit margin will not be higher, but if you hold them bit longer then you can make higher profits in future.
