On Sep 10 someone consolidated bitcoin from 829 addresses into address 32ZHZYwYATJj8jtoFvUQ9HEz7UoWnLgG5U then he moved the 45.5k BTC 540 times with 720 cash outs (total 1k BTC) at 26 exchanges and on Sep 14 he split the remaining 44.5 BTC again into 51 addresses. From the new addresses similar behavior continues.
It's not a whale. It's an exchange consolidating all the UTXOs and then probably cashing out people's withdrawals. I don't see anything special there.
The exchange is FTX -

This is a strange behavior. A smart money launderer would probably not co-spend 829 addresses. And a honest person likely would not do 540 transactions for cashing out because one typo or software error could move the $2bn unintentional as fee to a miner and he could have done this in one or two transactions.
What's your thought?
What makes you think someone was money laundering?

Exchanges and other Bitcoin accepting services such as online casinos carry out such types of consolidation transactions every other day.
