After a brief pullback, the coin resumed its ascent \u2014 by Wednesday the price had surpassed<\/a> $72,000.<\/p>\n That proved a local peak. On Thursday, March 26, bitcoin turned lower, sliding from $72,000 to $68,000 in a day.<\/p>\n The sell-off extended on Friday as the asset plunged<\/a> to $65,000. Prices reacted to reports of an escalation in the Middle East and outflows from ETFs<\/a>.<\/p>\n Spot bitcoin funds snapped a four-week run of inflows. From March 23\u201327 the products lost<\/a> $296m.<\/p>\n Ethereum ETFs saw outflows<\/a> of $206m.<\/p>\n Over the weekend bitcoin stabilised, holding just under $67,000 and losing 3% over seven days. Observers reckon the next leg hinges on macro and geopolitics.<\/p>\n The wider crypto market tracked the flagship and, as usual, reacted more sharply to sell-offs.<\/p>\n Ether fell 4%, XRP 5% and Solana 5.8%.<\/p>\n HYPE clung to tenth by market value, adding 2% on the week.<\/p>\n Total crypto capitalisation stands at $2.37trn, with BTC dominance at 56.1% and ETH at 10.1%.<\/p>\n The Crypto Fear and Greed Index<\/a> remains in \u201cextreme fear\u201d at 9.<\/p>\n The Miner Position Index (MPI) fell<\/a> to -1.04 \u2014 the third-lowest reading on record. CryptoQuant analyst Ignacio Moreno de Vicente called it a bullish signal.<\/p>\n Such levels indicate miners are sending fewer coins to exchanges than usual relative to the yearly average, structurally reducing sell pressure.<\/p>\n \u201cMPI reflects the relative behavior of sellers, but does not show who absorbs the supply. Without a clear expansion of demand (spot flows, ETF inflows or positioning in derivatives), a low MPI alone cannot deliver a sustained upward move,\u201d de Vicente added.<\/p>\n<\/blockquote>\n The signal strengthens when the gauge turns up from lows, pointing to a return of activity as conditions improve.<\/p>\n Meanwhile, CoinShares analysts recorded<\/a> a capitulation by 20% of bitcoin miners. They said the fourth quarter of 2025 was the toughest for miners after the latest halving<\/a>. The weighted-average cost per coin among public firms reached $79,995.<\/p>\n At risk are operators with outdated hardware and high power costs.<\/p>\n Mid-generation rigs run below breakeven at the current hashprice, especially if electricity is $0.05\/kWh or higher. To stay profitable, they need cheaper tariffs.<\/p>\n Sideways bitcoin prices would worsen matters. Head of research James Butterfill said a prolonged slump would force inefficient capacity offline, slowing hashrate growth and eventually rebalancing returns.<\/p>\n Large miners also kept selling reserves. This week MARA Holdings said<\/a> it sold 15,133 BTC for roughly $1.1bn.<\/p>\n The proceeds will go towards repurchasing the company\u2019s own bonds.<\/p>\n The non-profit Ethereum Foundation unveiled<\/a> a roadmap to protect the blockchain from quantum computers, envisaging four hard forks<\/a>.<\/p>\n Key updates include:<\/p>\n The transition will touch all three layers of the protocol \u2014 execution, storage and data availability.<\/p>\n The foundation estimates \u201ccryptographically significant\u201d machines are at least eight, perhaps twelve, years away. Preparation, however, should begin now.<\/p>\n \u201cQuantum computing will ultimately break public-key cryptography, which provides ownership, authentication and consensus across all digital systems. Work must begin long before the threat becomes reality,\u201d the Ethereum Foundation noted.<\/p>\n<\/blockquote>\n The team aims to complete the network overhaul by 2029, though full migration will take several more years.<\/p>\n OpenAI announced<\/a> it was shutting its Sora app for AI video generation, without giving reasons.<\/p>\n Despite buzz after the launch of the updated Sora 2 model and its eponymous social network, the product failed to retain users. Downloads peaked in November 2025 at about 3.3m across the App Store and Google Play, but fell to 1.1m by February.<\/p>\n The Sora social network was conceived as a TikTok analogue with an AI bent. Its signature cameos feature let users scan their faces, create realistic deepfakes of themselves and share them with others to generate collaborative clips.<\/p>\n The Sora 2 model remains available, but on a paid basis via ChatGPT.<\/p>\n OpenAI also scrapped<\/a> its Instant Checkout feature, launched in September 2025. The tool enabled users to confirm orders, delivery and payment without leaving the chatbot interface.<\/p>\n \u201cThe company underestimated how complex implementing transactions would be. On the one hand, it\u2019s a little surprising, but on the other \u2014 it\u2019s not easy for retailers either,\u201d said Bob Hetu, an analyst at research and consulting firm Gartner.<\/p>\n<\/blockquote>\n After reviewing project strategy, OpenAI plans to make ChatGPT a \u201csuper-app\u201d \u2014 a single ecosystem for the Codex coding assistant, the Atlas browser and the chatbot, housed in one desktop application. Sora is likely to be folded in as well.<\/p>\n Also on ForkLog:<\/strong><\/p>\n Telegram founder Pavel Durov said<\/a> the messenger had fully redeemed the convertible bonds issued five years ago.<\/p>\n In March 2021 the company issued<\/a> five-year dollar notes at 7% for a total of $1bn. The bonds gave investors the option to convert into Telegram equity at a 10% discount to the notional price in the event of an IPO<\/span>.<\/p>\n In May, on the same terms, the company additionally issued<\/a> $750m of bonds.<\/p>\n Durov said the monetisation strategy adopted five years ago allowed the messenger to turn profitable as early as 2024.<\/p>\n \u201cAs a result, our new bond issue last year was oversubscribed,\u201d he added.<\/p>\n<\/blockquote>\n Media had reported that Telegram planned<\/a> to list by end-2023. Closer to that date, reports appeared<\/a> of the IPO being pushed back by another 18\u201324 months.<\/p>\n Telegram had previously conducted<\/a> debt placements; a quarter of one $270m tranche was bought back<\/a> by Durov himself.<\/p>\n ForkLog discussed<\/a> with lawyers and market participants the contentious aspects of forthcoming crypto regulation in Russia.<\/p>\n We examine why the notion of AI as a simple digital adviser is becoming obsolete<\/a> \u2014 and how new blockchain standards turn algorithms into full-fledged market actors.<\/p>\n This week also brought two \u201cDeconstruction\u201d episodes: a special episode<\/a> unpacking Russia\u2019s draft crypto law, and the regular podcast<\/a> on the week\u2019s news.<\/p>\n","protected":false},"excerpt":{"rendered":" Bitcoin slipped below $67,000; miner activity hit a record low; Ethereum\u2019s quantum defence is slated for 2029.<\/p>\n","protected":false},"author":1,"featured_media":95704,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"select":"1","news_style_id":"1","cryptorium_level":"","_short_excerpt_text":"Bitcoin below $67,000; miners quiet; Ethereum plots quantum defence by 2029.","creation_source":"","_metatest_mainpost_news_update":false,"footnotes":""},"categories":[3],"tags":[1244],"class_list":["post-95703","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news-and-analysis","tag-weekly-summary"],"aioseo_notices":[],"amp_enabled":true,"views":"109","promo_type":"1","layout_type":"1","short_excerpt":"Bitcoin below $67,000; miners quiet; Ethereum plots quantum defence by 2029.","is_update":"","_links":{"self":[{"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/posts\/95703","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/comments?post=95703"}],"version-history":[{"count":1,"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/posts\/95703\/revisions"}],"predecessor-version":[{"id":95705,"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/posts\/95703\/revisions\/95705"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/media\/95704"}],"wp:attachment":[{"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/media?parent=95703"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/categories?post=95703"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/forklog.com\/en\/wp-json\/wp\/v2\/tags?post=95703"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"image\"](\"https:\/\/forklog.com\/wp-content\/uploads\/img-b362e7d8b410a57f-398938657205158-1024x512.png\")
