Difficult to tell. I've been looking at buying in but don't even know when! Last week I was going to bite the bullet and go in when it was around 300USD and thankfully I didn't. Not sure what the main reason for the sell-off is but I presume it may have something to do with all these ICOs cashing out for fiat + correction?
