Someone keeps posting a picture in the group saying, "These two transfers are too coincidental, there must be something going on."

I now tend to break down "coincidence" first: Is it the same source of funds being split?
Is there a hot wallet at an exchange acting as an intermediary?
Are there contracts batch issuing tokens/rewards, making a bunch of people look connected…
To put it simply, many "synchronizations" on the chain are actually the same automation running.

Recently, before and after the upgrade of that mainstream public chain, everyone is guessing whether to migrate or not.
I actually want to see if the fund flow has changed:
Did the number of bridge entry points increase?
When crossing chains, do they first go around major exchanges?
Have the project team wallets prepared gas and fees in advance?
Anyway, I’m okay with being a bit slow to react; first, clarify the path, then decide whether to get nervous.
