Bitcoin and numerous other cryptos' graph signatures look identical last night?

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.

I don't.. really think this is the case.. bitcoins and other cryptocurrencies are way different thus.. their graph showing striking similarity maybe.. Something.. of the moment or..so.. its not really possible for someone to manipulate every other cryptocurrency at the same time and i doubt if anyone would have that much funds to do so..and for joint..funds...one would need a yes from..every investor..and..thats practically impossible...
Thus I don't think this is the case.

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.

it is not exactly automation, it is because these markets are linked together so when one moves, other move with it.
for example ETH is 0.045BTC and at the same time it is worth $371
that means bitcoin was $8244.44

now lets say bitcoin drops to $7800, as i said these markets are linked. if ETH stays at 0.045BTC that means it is losing value because 0.045BTC is now worth $351 so it has to rise against bitcoin but to rise, someone has to buy it and there is always more people trading in the bitcoin markets than in fiat market that means price against USD drops because it can not go up against bitcoin.
the final result of this is ETH at 0.0458BTC and $357 in other words a drop.
