I wish there was a way to upload images to these posts.  The graphs are indeed strikingly similar.  Bitcoin, Ethereum, Litecoin, and others experienced a dramatic drop last night at 22:00 and then popped back up to their original numbers shortly there after.  It just seems too identical.

Can someone explain how it is possible for numerous cryptocurrencies to have an identical graph signatures at a given time of day?  Makes me suspect that something automated is manipulating the prices.
