its not a "user speculating"
its an exchange organising its cold store

the only speculating i see is the social drama of the reddit poster and this topic creator

exchanges have always been organising its coldstore daily for years
so many examples.. heres one

this is an exchange re-accumilating its cold stores into one main address after reorganising

there are many other examples.. just the other week people were screaming about "6k moved" "66k moved" "8k moved"
which were all the same thing

so relax its not user movements. its just exchanges doing what they do regularly
