Bitcoin ripped past 77,000 dollars in its best week since 2023, wiping out more than 4 billion dollars in short bets over two days. Spot Bitcoin ETFs pulled in 606 million on Wednesday alone, and Strategy's treasury climbed back into the black. Meanwhile, xAI dropped Grok 4.6 on Amazon Bedrock with a 500,000 token context window, Metaplanet is planting a Bitcoin treasury flag on Nasdaq, and a contentious Bitcoin hard fork tied to BIP-110 is raising replay attack alarms. Let's get into it.
Bitcoin's move this week has been violent in the best way for bulls. Price cleared 77,000 dollars, touched 78,449, and briefly challenged 80,000 overnight before easing back. That's a 24% gain since Monday, and it reclaimed the 200-day moving average for the first time in nine months. The setup now points toward a golden cross, and shorts are getting demolished — over 4 billion dollars in liquidations across two days, with Thursday alone setting a record going back to 2021.
So what's driving it? The consensus points to the US Treasury expanding bond buybacks. This isn't quantitative easing, and it isn't yield curve control, but the market is reading it as a liquidity signal. Longtime bond investor Mark Connors thinks routine Treasury buybacks could set up Bitcoin's next leg toward 180,000 dollars. Add in the fact that US federal debt just crossed 40 trillion dollars, and the hard-asset thesis basically writes itself.
Institutions are showing up. Spot Bitcoin ETFs took in 608 million dollars on one day, Ether ETFs 221 million — the biggest Ether inflow since October. Standard Chartered's Geoff Kendrick is now waffling on his 100,000 dollar year-end target, saying it might be too low, and pointing to the previous all-time high near 126,000.
Analysts are split on whether this is the start of a proper bull run or a violent squeeze inside a longer chop. The classic bottom signals are all there — sharp spikes, forced short covering, capitulation from the bearish side. But macro risk hasn't disappeared. Weekend liquidity is thin, and 80,000 dollars is the next real test. If it breaks cleanly, the technical picture opens up fast. If it rejects, expect a nasty wick.
Strategy, by the way, is now sitting on a 1.4 billion dollar unrealized profit on its Bitcoin stack, and the stock jumped 10% in Friday pre-market to 120 dollars. Michael Saylor's patience is paying off again.
Metaplanet is making its boldest move yet. The Tokyo-listed Bitcoin treasury company — now the third-largest corporate Bitcoin holder behind Twenty One Capital and Strategy — is taking a controlling stake in Nasdaq-listed Super League Enterprise, and rebranding it Superplanet.
The mechanics: Metaplanet is contributing 2,100 BTC plus 2.5 million dollars in cash, roughly 132 million dollars worth of Bitcoin, into Super League. That 2,100 BTC comes out of Metaplanet's existing 43,000 BTC treasury — about 4.9% of its stack. It's not a new purchase, it's a redeployment. Post-close, Metaplanet will own roughly 93 to 95% of Superplanet's common stock, with a five-year lock-up signaling long-term commitment.
Why does this matter? Metaplanet now has two listed vehicles to raise Bitcoin-denominated capital — Superplanet on Nasdaq for US markets, and Metaplanet itself in Tokyo. That's dual-market access to deeper capital pools, US financial instruments, potential Bitcoin-backed loans, and a friendlier regulatory environment for corporate crypto treasuries. Super League keeps operating its gaming and immersive media business as a division, but the real product here is Bitcoin per share, growing without dilution.
And Metaplanet isn't alone. Chinese insurtech Zhibao Technology just closed a 154.7 million dollar private placement funded entirely in crypto — 2,380 Bitcoin contributed directly to the company wallet by non-US investors, in exchange for shares and warrants. That's an all-crypto treasury raise, which is a genuinely new structure.
The caveat: not everyone is expanding. Strategy has paused new purchases and is selling some holdings to fund dividends and buybacks. The corporate Bitcoin treasury trend is bifurcating — the disciplined operators are scaling globally, while marginal players are getting shaken out. Metaplanet is clearly betting it belongs in the first camp.
xAI shipped Grok 4.6, and it's now generally available on Amazon Bedrock. The headline specs: 500,000 token context window, four configurable reasoning tiers from low to xhigh, and pricing at 2 dollars per million input tokens and 6 dollars per million output — with cached input at just 30 cents per million. That's roughly a 60% discount to comparable frontier models, and it's competitive with GPT-5.6 and Claude on benchmarks, particularly on coding.
The more interesting angle is agentic. Grok 4.6 is optimized for long-running agents. xAI is pushing a persistent cloud-based AI agent called Grok Bot that can manage multi-step workflows, run extended research, iteratively verify its own work, and act through external connectors — messaging, approvals, the whole autonomous assistant playbook. Multimodal has been upgraded too, with better chart and diagram interpretation and video generation for explaining complex concepts.
On Bedrock, the pricing tiers up slightly for regional profiles — 2.20 in, 6.60 out — with cross-region global at the base rate. It supports Responses, Chat Completions, and Converse APIs, plus prompt caching. Server-side tool use and structured outputs aren't supported yet, which is worth noting if you're building.
And there's a strategic story underneath. According to Motley Fool coverage, xAI just closed a 60 billion dollar deal for Cursor, the code editor with over 50,000 enterprise customers including roughly two-thirds of the Fortune 500. That developer interaction data feeds directly into xAI's Composer coding model, with Composer 3 expected soon. Combine that with xAI's Colossus compute clusters — 1.4 gigawatts of nameplate compute at the end of June, targeting over 2 gigawatts by year-end — and you have vertical integration that competitors renting capacity simply can't match on unit economics. Grok 4.7 is reportedly weeks away.
The bear case: xAI still doesn't have a recurring profit center like Google Search or Microsoft Office. But on price, performance, and developer distribution, they've closed the gap fast.
Bitcoin protocol politics got messy this week. Two hard fork proposals are floating around, and both are stress-testing what "Bitcoin" even means.
First, BIP-110 and the RDTS minority chain. Miner support was weak — around 2.53% — and the minority chain stalled after August 8. But the debate over replay protection is the real story. Without automatic cross-chain replay protection, a transaction on one chain can be valid on both, meaning your BTC spend could accidentally move the forked asset too. Bitcoin Knots is proposing an opt-in sighash option to grant chain-specific validity. Luke Dashjr's position is blunt: replay protection is the airdrop altcoin's responsibility — he's literally calling it "Spamcoin" — and legitimate Bitcoin transactions should stay valid on Bitcoin. In a related shake-up, Dashjr was removed from the Bitcoin BIP repository after a contentious split, with editors revoking his access despite no formal removal procedure existing.
Second, Paul Sztorc of LayerTwo Labs is planning an August hard fork called eCash, targeting block 964,000. Holders would get 1 eCash per 1 BTC, with a Bitcoin Core-style base layer plus Drivechain-style sidechains. Sztorc says eCash spends should be blocked from replaying on Bitcoin by default — but he's also warned this depends heavily on wallet and custodian software. His own guidance: avoid untrusted claim tools, unofficial wallets, and phishing prompts.
Zoom out and there's a bigger conversation happening about BIP 361, the post-quantum migration proposal. Three phases: block new sends to quantum-vulnerable addresses, then invalidate ECDSA and Schnorr spends from vulnerable UTXOs at the consensus layer, then potentially unlock frozen coins via zero-knowledge proofs. Core L1 upgrades are pegged around 2029, with full migration taking 10 to 20 years. It's the most concrete plan Bitcoin has for the quantum question, but it forces a choice between frozen coins and stolen coins that the community has never had to make.
And on the wallet security front: Coldcard shipped a firmware update after the 114 million dollar theft that hit users recently. Three weeks of review turned up additional bugs unrelated to the original flaw. But — critical caveat — updating firmware does not make an already-compromised wallet safe. If you were affected, you need new seeds, not a patch.
Bitcoin at 77,000 with institutions piling in, corporate treasuries expanding across borders, and Grok going agentic on Bedrock — the infrastructure of the next cycle is being laid in real time. Watch whether 80,000 breaks cleanly next week. That's the tell.
