Bitcoin rose 23.5% over the week to $77,559 after briefly topping $79,000 on Friday, with Barchart noting that the cryptocurrency had moved above its 200-day moving average for the first time since November 2025. The indicator is widely used to assess longer-term trends, and a move above it is often viewed as evidence of bullish momentum. Ethereum gained 31.1% to $2,456, Solana rose 28% and XRP surged 53.3% to $1.52. Bitcoin and Ether ETFs attracted more than $2.61 billion in combined inflows last week, while Micheal Saylor's Bitcoin investments through Strategy moved above their $75,385 breakeven point. Polymarket odds of Bitcoin reaching $90,000 before 2027 reached 48%, and publicly listed crypto-related companies including Canaan, Metaplanet, Coinbase and Robinhood posted double-digit gains. The total crypto market capitalization reached $2.63 trillion, according to CoinMarketCap. The rally unfolded alongside renewed concern over the US debt burden, which crossed $40 trillion, and debate over Treasury policy, inflation and deficit spending. Ray Dalio said investors should allocate about 15% of their portfolios to gold and a bit of Bitcoin, while estimating that a US debt crisis could arrive in three years, give or take two, if current policies do not change. US President Donald Trump again urged Congress to pass the CLARITY Act after meeting Coinbase CEO Brian Armstrong and Gemini co-founders Cameron and Tyler Winklevoss. The House of Representatives passed the market-structure bill in July 2025, and a procedural vote scheduled for September 15 requires 60 votes. The SEC (US securities regulator) proposed exemptions that could allow crypto projects to issue up to $5 million in tokens over four years and up to $75 million over 12 months under stricter requirements, alongside a safe harbor from treatment as investment contracts. CFTC (US derivatives regulator) chair Michael Selig said the agency would pursue its own crypto rules if the bill fails in the Senate. Standard Chartered's Geoff Kendrick said Bitcoin could approach its $126,000 all-time high before year-end and that the bank's $100,000 forecast may be too low, while Bitget CEO Gracy Chen expects Bitcoin to finish the year within $10,000 to $20,000 of current levels. Separately, MANTRA's token fell 18% to an all-time low of $0.004126 before MANTRA Chain halted block production over an unexplained incident, freezing endpoints and transactions. The project later said on Aug. 22 that a vulnerability in its Cosmos-EVM module had been fixed, the network had resumed and no user funds were affected.
