A softer dollar has also provided support to cryptocurrencies.The latest Bitcoin rebound has shown signs of being more than a short-lived relief rally. CNBC Pro reported on August 25 that Bitcoin had gained about 22% over the previous week, with the move taking it above its 200-day moving average, a widely watched indicator of its longer-term price trend.CNBC Pro also pointed to the technical strength of the rebound, noting that the combination of a sharp weekly gain and a move above the 200-day moving average has historically been associated with further gains.Institutional buying has added to the momentum. US spot Bitcoin exchange-traded funds recorded $1.92 billion of inflows in a single week, signalling renewed demand from large investors.Regulatory expectations are another factor. US lawmakers are preparing for a key Senate vote on the CLARITY Act in mid-September. The proposed legislation aims to establish a clearer regulatory framework for digital assets in the US.Crypto is moving beyond tradingThe latest crypto rally is also unfolding alongside growing use of blockchain technology for traditional financial assets.South Korean trading giant POSCO has moved its trade receivables onto the Avalanche blockchain, showing how blockchain networks are being used beyond cryptocurrencies.Meanwhile, Bitwise has launched automated portfolios that convert tokenised stocks on Coinbase into themed baskets focused on areas such as artificial intelligence and robotics.These developments point to a broader push towards tokenisation, where traditional assets can be represented and traded using blockchain technology.Where can you spend crypto?Crypto payments are also expanding across a range of businesses.Shopify supports cryptocurrency payments for merchants, while Microsoft has accepted Bitcoin for certain digital purchases. Fast-food chains such as Steak 'n Shake and Chipotle have also entered the crypto payments space.Electronics retailer Newegg has supported Bitcoin payments, while luxury brands Gucci and Balenciaga have experimented with cryptocurrency payments in select markets.For now, the August rally is being driven by a mix of institutional buying, easier financial conditions and hopes of clearer regulation. With Bitcoin back above $80,000 and altcoins posting even stronger gains, the next test is whether this broader rally can hold.
