Calle launches BitNotes, a multi-mint Cashu wallet that prints ecash on paper

Grade Bbullish AI signal$BTC

Calle has launched BitNotes, a free, open-source Cashu wallet that lets users print Bitcoin-based ecash onto physical paper notes with offline cryptographic verification. The multi-mint wallet supports Lightning payments, Ark for bringing on-chain Bitcoin into the wallet, and a Mobile Money bridge for Rwandan Francs, with availability currently limited to Android and macOS. BitNotes could expand Bitcoin's use for cash-like and offline payments, but the lack of disclosed security audits and adoption figures may limit early user confidence.

Bullish strength: 70/100

Physical ecash notes can be verified offline using mint public keys.
Lightning integration supports digital ecash transfers and movement of value.
The multi-mint design allows transactions across independent mints, reducing dependence on a single operator.
Mobile Money support includes a bridge for Rwandan Francs.

Bearish strength: 30/100

No external security audits have been disclosed.
No concrete adoption figures are available.
Users remain exposed to mint redemption risk, and paper notes can be lost, damaged, or stolen.

Bitcoin ETFs log $525M inflow as Ethereum ETFs attract $14M

U.S. spot Bitcoin ETFs attracted $525 million in net inflows on October 21, marking their largest single-day haul in nearly a month and reversing October's cumulative flows into positive territory. BlackRock's IBIT and Fidelity's FBTC led with approximately $235 million and $213 million, respectively, while Ethereum ETFs added $14 million, ending five consecutive sessions of outflows but remaining down about $1.07 billion for October. Sustained Bitcoin ETF demand could support BTC sentiment, although limited price gains despite heavy inflows and continued Ethereum fund outflows may signal persistent market uncertainty.

Bitcoin ETFs Pull $1B in 3 Days as BTC Revisits Key $80.2K Cost Basis

Bitcoin returned from $85K to $81K overnight after an Iran strike report and an Asian technology-stock rout erased the rebound. Oil was back above $112. Spot Bitcoin ETFs recorded more than $1 billion in inflows over three days. The average cost basis for ETF holders is around $80.2K, making that level a key reference point for the ETF cohort. Tesla's 11,509 BTC remained unchanged, according to the source. The U.S. has finalized its first stablecoin rulebook, while 100 crypto projects have shut down in 2026, highlighting a focus on compliance and cash flow.

ARK 21Shares Bitcoin ETF - 21Shares Us Llc To Terminate Support Services Agreement With Ark Effective Dec 22, 2026 - SEC Filing

ARK 21Shares Bitcoin ETF will undergo a name and ticker change, with its trust set to become the 21Shares Bitcoin ETF and its ticker changing to TBIT. An SEC filing states that the trust name change is scheduled for December 15, 2026, while 21Shares US LLC will terminate its support services agreement with ARK effective December 22, 2026. The changes could reshape the ETF's branding and operational arrangements, though their direct impact on Bitcoin demand remains uncertain.

Claude AI Cracks Satoshi’s 17-Year Bitcoin Mystery

A developer has reportedly used Anthropic’s Claude Opus 5.5 to recreate Bitcoin’s original preserved 2009 Windows executable, matching its SHA-256 hash exactly and reproducing every byte. The reconstruction suggests Satoshi Nakamoto used Windows XP and MinGW GCC 3.4.5, while the recovered executable dates to January 10, 2009, rather than Bitcoin’s January 8 announcement day. The discovery could strengthen historical confidence in Bitcoin’s preserved source code, but its immediate security implications appear limited and the original launch-day executable remains missing.
