MARA moves another 1,000 BTC to BitGo as October transfers pile up

What happened

MARA Holdings, a bitcoin mining company with publicly traded shares, sent 1,000 BTC to the custodian BitGo in a single transfer that was first highlighted by the tracking account Lookonchain. CryptoPotato reported that the coins were worth just over $80 million when they left, and that Lookonchain used the word "dumped" to describe the move. The tracker's data showed a string of small inflows of about 3.12 to 3.14 BTC, apparently mining rewards, before an address tied to the miner pushed out roughly 1,000 BTC valued at $80.19 million to a known BitGo address.

A day later, 99Bitcoins reported that MARA had made a second transfer of exactly 1,000 BTC to BitGo, worth about $81 million, early on Wednesday, October 28. That made it the second such movement in two days and, by the outlet's count, the fourth large transfer from the company in October. Lookonchain put the value of the second lot at $80.66 million in its post.

The market took it in stride. 99Bitcoins noted that bitcoin was up about 2% over 24 hours and trading near $81,577 on Binance at the time of writing, with the first of the two BitGo lots already broken up and sent onward. CryptoPotato, publishing before the second transfer was reported, said the asset was a few hundred dollars below $80,000.

Why it matters

Transfers from miners draw attention because they can come before sales, and MARA is one of the largest corporate holders of bitcoin. Hupzy, an AI agent account formerly associated with Spot On Chain, called the 1,000 BTC move a "structural supply overhang", arguing that when a major miner offloads a chunk that size in one go it can soak up much of the available buying interest and leave fewer bidders to support the price.

The company's own disclosures make each movement closely watched. MARA's filings say it sells the bitcoin it mines on an ongoing basis and may sell more of its holdings from time to time, so coins arriving at a custodian are read by traders as a possible precursor to a sale, even though, as 99Bitcoins stressed, the blockchain record on its own does not prove one. The first lot was split at 07:13 UTC on Wednesday into 16 pieces of between 21.5 and 108.5 BTC and sent to new addresses, a pattern the outlet said is common when coins are delivered to several buyers; none of the recipients is labelled.

What the data shows

MARA reported holding 35,577 BTC at the end of June 2026, down from 53,822 BTC at the close of 2025, after selling about 23,093 BTC for $1.63 billion in the first half of the year, mostly to buy back convertible notes. Of what remained, 4,528 BTC was pledged as collateral and 4,742 BTC was lent out. The company mined 2,422 BTC in the second quarter, roughly 807 a month, and sold 2,213.

Before the two BitGo lots, Lookonchain had flagged 996 BTC sent to Galaxy Digital on October 8 and 1,000 BTC sent to Binance and Gate between October 14 and 19. Combined, that is about 11% of the 35,577 BTC MARA held at the end of June, or roughly five times its monthly production, and around $326 million at recent prices. For scale, 99Bitcoins noted that $23.9 billion traded across the market in the previous 24 hours. Both BitGo lots had sat untouched since October 7 and 8, 2025, when bitcoin traded above $121,000.

Background

MARA's second-quarter report, published in August, showed a $611 million loss with revenue down 27%. The company is buying a 505-megawatt gas plant in Ohio and weighing whether to shift as much as 90% of its mining capacity to AI computing. It has not yet set a date for third-quarter results; last year it reported on November 4, and that letter is where any October sales would first show up. CryptoPotato also noted, citing Bitcoin Treasuries, that Strive has overtaken MARA as the fourth-largest bitcoin holder after a series of purchases, including 6,182 BTC for $511 million, taking its stash to 43,000 BTC.

What is still unclear

What the transfers mean remains unresolved. The second 1,000 BTC lot was still sitting at the BitGo address, and the unlabelled receiving addresses mean the onward movement of the first lot cannot be tied to specific buyers or sellers. MARA did not comment on the transactions in either report.

What to watch

Attention now falls on BitGo's address: if the second lot is split the same way as the first, 99Bitcoins argued, the pattern would be hard to read as anything other than selling. MARA's third-quarter update is the next scheduled disclosure where October sales would appear. On price, Doctor Profit has suggested bitcoin may be forming a local bottom near $80,000, pointing to $80,000 to $81,500 as the entry range for many ETF investors and treasury firms, while Ali Martinez noted a break below a rising parallel channel on the four-hour chart and said a failure to reclaim $82,000 could open the way for a drop of as much as 10%.
