Why do most coins follow the same pattern? Bots? CEX manipulation?

If you j ust look at all the charts, for the most part they all follow the same pattern. Even though a few like SOL deviate a bit from the pattern, every coin followed Bitcoin on this last little mini pump. So what gives? It's obvious this isn't humans, is it bots? CEXs doing some kind of balancing act?

If it is bots, then who controls them? Do they just divide up everything into multiple coins all at once? It seems so manipulated and unnatural. It's almost like we are part of an index fund instead of individual coins since they all move together anyways.
