Bitcoin, ETH, XRP, DOGE, MSTR Cashtags Go Live on X Web, Musk Says Most Crypto Are Scams

X (formerly Twitter) rolled out its Smart Cashtags feature on the web in the US and Canada, embedding real-time charts and market data for cryptocurrencies and stocks directly into timelines. Supported crypto include BTC, ETH, XRP, SOL and DOGE; listed stocks include NVDA, TSLA, MSTR, MARA and COIN. The move could boost retail engagement and make X a trading-friendly feed, potentially increasing on-platform price discovery and short-term flows into featured assets. At the same time, Elon Musk’s testimony in the OpenAI trial — labeling “most” crypto assets as scams while noting Tesla and SpaceX retain sizable BTC holdings — injects mixed sentiment into markets. The combination of a product rollout that increases visibility for major tokens and negative public commentary from a high-profile influence creates a nuanced market impact: greater retail exposure and potential trading activity, offset by headline-driven skepticism.
