Nikita Bier, X's product lead and Solana ecosystem advisor, announced plans to introduce new features, including 'Smart Cashtags,' enabling users to trade stocks and cryptocurrencies directly from their timelines. Bier expressed a desire for cryptocurrency to become more widespread on X but criticized applications that incentivize spam, raids, and user harassment, stating these practices harm the experience of millions of users. The new features are expected to roll out in the coming weeks.
