From my experience, some similar coins can be divided into groups, whenever you see one of the coins pumping, the rest of the coins in the same group follows.
Usually these groups contain coins from the same category, example (memes, defi, etc..) and you can check it in the info tab on the coin page on Binance.
The groups i know about are
(Xrp - ada - pol)
(Sand - Mana - Gala)
(Atom - Dot)
(Lunc - luna - ustc)
