There is a long comb-like chain of transactions like this one:

https://kaiko.com/address/1JW6Vc76MKZU56ya8PKUGAoPetzLksT4Vn

Fat address of 1.3k BTC gets fully spend into a newly created address, also sheds one small amount to a random adress in the process. Frequently recirculated wallet creates artificial volume.

Maybe a strategy to get your transaction noticed by the miners? Maybe a mixer? Who knows?

EDIT:

Beginning is at: https://kaiko.com/transaction/9da21c708e83661bc8dbbb19c5b614...

with 2k BTC consolidated from lots of 27.61 BTC amounts. Looks more shady now.
