Arkham: Transfer of more than 80,000 BTC of ancient whales or perform migration due to address upgrade

On-chain analysis platform Arkham posted on the X platform that the ancient giant whale that had previously transferred more than 80,000 BTC may have been a migration operation due to the address upgrade, transferring the address starting with "1-" to the address starting with "bc1q-". So far, there is no sign that the ancient giant whale is selling its bitcoin.
