It's no dump. It's still within the same support and resistance bands that we've been in since hitting the low 3000s and bouncing back. Anything about 3500/3600 is nothing to worry about and anything below 4500 is nothing to get excited about.
If the prices keep steady at that range of $3500 and $3600, you may be right that this is not a dump. Especially if the market recovers soon. Let's wait and see. But, if the prices continue to decline, something is manipulating the market again.
