Le soleil se couche sur un mois d’octobre devenu morose pour Bitcoin, alors que la plus grande cryptomonnaie au monde fait face à la perspective réelle de deux mois consécutifs de baisse pour la première fois depuis des années, les traders de détail inondant les exchanges alors que les plus grands noms du secteur cartographient des horizons à plus long terme. Bitcoin reculait de 1,35 pour cent sur le mois au 19 octobre, une maigre ombre de la performance historique moyenne d’octobre de 18,40 pour cent, et un renversement brutal par rapport au rebond de 24,95 pour cent qui avait suivi le plongeon de 20,48 pour cent de juin. Le prix tenait à peine au-dessus de 81 000 dollars mardi, après être remonté vers 84 000 dollars après avoir brièvement franchi le seuil des 86 000 dollars plus tôt dans la session, mais ce rebond semblait fragile et contesté.
Illicit cryptocurrency volume reached an all-time high of $158 billion in 2025, a staggering 145 percent increase from the prior year, driven largely by sanctions-evasion infrastructure linked to Russia.
Les données on-chain dressaient un tableau saisissant de la divergence entre les petits traders et les baleines. Les dépôts liés aux particuliers sur Binance ont bondi de 7 milliards à 10,78 milliards de dollars sur les trente derniers jours, une hausse de 54 pour cent qui éclipsait largement la modeste augmentation de 9,5 pour cent des flux vers les baleines, qui ont atteint 4,6 milliards de dollars. L’écart entre les deux cohortes s’est creusé de 2,8 milliards à 6,18 milliards de dollars, ce qui signifie que les particuliers se séparaient de leurs pièces bien plus rapidement que les acteurs plus importants ne pouvaient les absorber. Pourtant, une lueur d’optimisme contracyclique transparaissait dans le comportement des grands poissons : la cohorte des baleines détenant entre 1 000 et 10 000 Bitcoin a inversé sa tendance à la distribution entre fin septembre et mi-octobre, réduisant leurs ventes de 62 600 pièces à seulement 5 230 pièces et inversant la dynamique vers l’accumulation. La tranche des détenteurs de 100 à 1 000 Bitcoin accumule en catimini depuis mi-juillet. La question technique centrale alors qu’octobre tire vers sa fin reste de savoir si cette résilience des baleines pourra servir de rempart contre la pression persistante des particuliers.
Marchés & prix
Ethereum, la deuxième blockchain en termes de capitalisation boursière, soignait également ses plaies mardi, évoluant dans une fourchette de 2 380 à 2 400 dollars et faisant face à des vents contraires tant de la faiblesse générale du marché que d’un échec de la dynamique à court terme. Les marchés de prédiction sur Polymarket assignaient une probabilité quasi unanime à une baisse d’Ethereum sous les 2 350 dollars, le consensus se cristallisant autour du seuil de 2 400 dollars comme niveau que les acheteurs n’ont pas réussi à défendre. La mise à niveau Glamsterdam, désormais en direct, n’a que peu fait pour enrayer la baisse à court terme, bien que la domination d’Ethereum dans les stablecoins, la finance décentralisée et les produits de tokenisation de niveau institutionnel continue de soutenir la demande structurelle à long terme.
XRP, which had surged to $1.70 before pulling back toward $1.30, was showing signs of a peculiar standoff among its largest holders. Wallets holding million-dollar positions had virtually ceased withdrawing tokens from exchanges, setting a five-year record for low withdrawal volumes among that cohort, an indication that the most sophisticated participants were choosing to hold through what they viewed as a temporary dislocation. Meanwhile, exchange deposits of XRP surged to 6.05 billion tokens over the thirty days ending October 19th, the highest in seven months, with Binance alone receiving 2.46 billion tokens. JPMorgan Asset Management, in its 2027 Long-Term Capital Market Assumptions report, predicted that Bitcoin would outperform all other major asset classes over the next decade, projecting a compound annual return of 10 percent, the most bullish outlook of any asset class in the bank’s survey.
Looking at Bitcoin’s technical picture, the cryptocurrency was clinging to its 50-day moving average as a last line of defense, with traders watching closely whether a breach below that level would trigger accelerated selling or prove to be a fertile buying zone. The four-hour chart had produced a deceptive breakout that reversed into a so-called fakeout, completing a Gartley pattern target near $81,336. The $81,500 area has emerged as the critical demarcation between a contained pullback and the start of something more damaging, and with retail momentum still pointed toward the exits and the macro environment still demanding a higher premium for risk, the path of least resistance as this trading day winds down remains firmly to the downside.
Institutionnel & ETF
ETF flows told a cautionary tale of institutional ambivalence. After periods of significant withdrawals earlier in 2026, Bitcoin spot ETFs had clawed back into positive territory, but the inflows were inconsistent and the October bleeding had already surpassed $1 billion across the category. Bitcoin ETFs saw a single-session inflow of $120 million on October 2nd while Ethereum funds bled $64.69 million on the same day, a microcosm of the divergent treatment these two assets receive from the regulated product complex. Sustained institutional demand, analysts caution, requires consistent allocation patterns rather than sporadic days of strong inflows.
Régulation & politique
La machine réglementaire de Washington continuait sa rotation pesante mais conséquence. Le cadre proposé « Regulation Crypto Assets » de la SEC a atteint sa date limite de commentaires publics le 20 octobre, closes the window for industry feedback on a rulemaking that would establish tailored offering regimes for certain crypto issuers while attempting to address longstanding definitional ambiguities around investment contracts. Commissioner Hester Peirce, whose departure effective October 2nd left the commission one seat short, had long championed a more accommodating approach to digital assets, and her absence is likely to shape the tone of any final rules that emerge from this process. The Federal Reserve, for its part, held steady at 3.65 percent on reserve balances at its most recent unanimous vote, though the broader rate environment remained a source of anxiety: the 10-year U.S. Treasury yield had briefly touched 5.34 percent following a hotter-than-expected September CPI print, a level not seen in generations, before retreating during a technology-sector sell-off. Expectations running toward year-end cluster around 4.25 percent, a trajectory that keeps expensive money a headwind for assets that generate no guaranteed cash flow.

The crime landscape cast a long shadow over the industry’s aspirational narrative. TRM Labs published its 2026 Crypto Crime Report, revealing that illicit cryptocurrency volume reached an all-time high of $158 billion in 2025, a staggering 145 percent increase from the prior year, driven largely by sanctions-evasion infrastructure linked to Russia. A ruble-pegged stablecoin called A7A5 processed more than $72 billion in total volume, with a single wallet cluster associated with that sanctions evasion network responsible for at least $39 billion in 2025 transaction value. The $1.46 billion Bybit breach from earlier in the year still accounted for the bulk of losses from hacks, even as the overall number of incidents declined. The report’s authors were careful to note that illicit activity represented only about 1.2 percent of total on-chain volume, but they introduced a new metric measuring illicit actors’ share of deployable capital, which came in at 2.7 percent, suggesting a concentration of risk that raw volume figures obscure.
Cybersecurity researchers were contending with a cascade of vulnerabilities across traditional software infrastructure. Go programming language maintainers released emergency updates on Tuesday blocking eight intermediate certificate authority keys operated by the Indian firm eMudhra after those keys were found to be compromised. Any holder of one of these keys could issue fraudulent certificates that browsers would accept, making the exposure severe and far-reaching. A proof-of-concept exploit was published for a critical path traversal flaw in Fortinet’s FortiSIEM security monitoring platform, carrying a vulnerability severity score of 9.4 out of 10 and potentially allowing unauthenticated remote code execution. Ransomware groups including Qilin and INC were found to be actively exploiting a patched authentication bypass vulnerability in Palo Alto Networks’ PAN-OS and Prisma Access products to establish unauthorized VPN connections. Separately, a Chinese-speaking criminal operation was observed using autonomous AI agents to probe and breach company websites, targeting more than 1,200 domains, including infrastructure belonging to farm-equipment manufacturer Deere and major appliance brands, with operators leaving their control panels exposed on the public internet.

In the infrastructure layer, Solana’s much-anticipated Alpenglow upgrade was set to go live on October 21st, targeting significantly faster finality while preserving the blockchain’s existing execution environment. The upgrade represents the network’s most consequential technical catalyst of the year and comes at a moment when SOL has fallen less sharply than XRP this month, though both assets are nursing losses. ZENDEX, a privacy-focused decentralized exchange, launched its public testnet on Tuesday following completed audits by Hacken and Dual Defense, promising users protection for trading strategies and order details on public blockchains. Chainlink’s CCIP 2.0 continued to build its narrative around institutional-grade compliance features for cross-chain settlement, positioning the oracle network as critical infrastructure for the tokenized asset economy that regulators and banks are slowly beginning to embrace.
