Yes, the 1,000 BTC (~$80.19M) move attributed to MARA Holdings was flagged about 6 hours before the posts, with lookonchain saying it "dumped" 1,000 BTC (post) and citing Arkham's MARA pool page.

BitcoinArchive described the same transfer as "MARA SENDS 1,000 BTC TO BITGO, WORTH $80M" and noted "Arkham claims it was a sale" (post), echoed in Korean Telegram as "1000 BTC 매도 추정" (message).

That is a transfer to BitGo-labeled custody, not confirmed on-chain as a market sale, and no statement from @MARA confirms a sale. Its recent X posts stop at Oct. 7 and mention only AI summit, ERCOT sites and Q2 results.

BTC itself was quoted around $80,178 on Binance spot, $80,168 on OKX spot and $80,039.8 on Kraken spot at the time checked. For a miner, moving ~1,000 BTC to a custodian is routine treasury or collateral handling, which is why BitcoinArchive called it "business as usual."
