Bitcoin news today is dominated by three converging forces — a resilient price holding near $81,500 despite a brutal inflation shock, a wave of institutional buying that is drawing fresh Wall Street attention, and a landmark quantum security push from one of the world’s largest crypto custodians.
The macro trigger arrived mid-week when U.S. producer prices rose 1.3% in September — the largest monthly gain since March 2022 — sending Bitcoin briefly below $80,000 before buyers pushed it back to $82,721.
Bitcoin absorbed the hottest wholesale inflation print in years and a broken floor, yet falling bond yields did much of the rescuing, while ETF money largely stayed on the sidelines and leverage remained elevated.
U.S. spot Bitcoin ETFs recorded $409.2 million in net outflows between October 12 and 16, while rising geopolitical tensions added further pressure to the market.
Although ETF outflows have eased from the prior week, Bitcoin is still struggling to recover above $84,000.
As of October 18,
Bitcoin’s price stood at $81,736.56 with a 24-hour trading volume of $6.15 billion.
Shorter-term moving averages favored sellers while longer-term averages continued to support buyers, with the RSI sitting at 46 and a neutral technical rating overall — support clustered around $81,000 and resistance extending toward $82,500.
Adding a longer-term headline to the mix, Coinbase dropped a significant technical paper on October 13 calling for an urgent start to Bitcoin’s quantum-resistance upgrade.
Coinbase has called for a multiyear Bitcoin quantum resistance plan, urging developers to begin preparing for a transition toward post-quantum cryptography before existing digital signatures become vulnerable to practical attacks.
About one in every twenty bitcoin in circulation sits in a Coinbase wallet, held on behalf of banks, asset managers, and hedge funds — concentration that forms part of the exchange’s stated motivation for pressing early action.
Google researchers have suggested a cryptographically relevant quantum computer capable of reverse-engineering a private key from a public key could exist by 2029, and Coinbase’s argument is that Bitcoin’s decentralized design means changes take years to agree on and implement, so the work has to begin now.
Coinbase’s quantum advisory board estimated in April 2026 that approximately 6.9 million BTC had potentially exposed public-key information, though this does not mean those holdings have been compromised.
Coinbase stressed that the post is intended for discussion and does not represent an approved migration plan or final company position.
On the institutional front, Bitcoin news today includes a notable Wall Street upgrade tied to corporate treasury activity.
TD Cowen increased its price target on Strive, Inc. by about 27%, from $44 to $56, while retaining a Buy rating, citing the firm’s bitcoin buying activity, which has already surpassed analysts’ projected total for the full fourth quarter after only a brief period of acquisitions.
Strive’s bitcoin holdings advanced to 35,595 BTC, valued at roughly $2.9 billion at prevailing prices, up from 28,000 BTC at the end of September — a nearly 7,600-coin increase that exceeded the prior estimate of 4,750 BTC for the entire quarter.
These steps moved Strive into fourth place among publicly traded companies ranked by bitcoin treasury size, just ahead of MARA Holdings.
Strive plans to raise $630 million through a preferred stock offering to fund additional BTC purchases without diluting common shares, with the offering scheduled to close on October 20.
For holders and traders, the picture is a mixed but not alarming one. The price has proven it can absorb bad macro news without collapse, yet institutional buying through spot ETFs remains weak enough to limit upside momentum. The quantum security story carries no immediate threat —
no publicly demonstrated quantum computer has successfully broken Bitcoin’s signatures at the scale required for practical theft, and Bitcoin holders face no mandatory post-quantum migration deadline.
Still, Coinbase’s call to action is a signal that the industry’s most serious custodians are treating long-term security as a now-or-never planning exercise.
What to watch next:
CryptoQuant’s comparison shows Bitcoin sitting 3.2% below its October 1 opening price by mid-month, while the same point in previous Octobers has historically produced an average gain of 6.7%.
Whether the second half of October can close that seasonal gap will be the defining technical question for the weeks ahead. Monitor spot ETF flows for signs of renewed institutional conviction, and watch the $80,400 level as the key near-term support floor that analysts have flagged as critical.
