It's quite worrying if there are individuals who have the power to manipulate the market in such a manner.

Hello all, this is my first post on Bitcointalk. So, admin, please forgive me if I've broken any rules with this post lol.

I've just woken up quite randomly in the middle of the night (too early for me), and I thought I'd have a quick glance at how the market in general is doing and some of the coins I'm particularly interested in investing in. I know, sad.

As I was looking at the charts on coinmarketcap and cryptocompare, at around 4:36AM / 4:37AM GMT to be precise, I noticed that nearly every single chart for each coin had a similar pattern to it. See attached images. Now, is it just me, or is it too much of a coincidence that they are ALL following the same trend? Is this normal? Or am I right to think it's not normal, and there is some form of market manipulation going on? Bots?
