Elon Musk’s X to enable crypto and stock trading with Smart Cashtags

Smart Cashtags, a feature under development at Elon Musk’s X to refine how assets such as stocks and crypto are integrated into the platform, will let users trade them straight from the timeline, Nikita Bier, X’s head of product, said Saturday.

Bier framed the move as part of an effort to support crypto without enabling behaviors that degrade the platform’s social experience.

“I genuinely want crypto to proliferate on X, but applications that create incentives to spam, raid, and harass random users are not the way. It meaningfully degrades the experience for millions of people — only to enrich a few people,” Bier said, responding to an X user who noted that the platform had been shutting down crypto apps without offering enough pro-crypto features.

“And yes, we are launching a number of features in a couple of weeks, including Smart Cashtags that will enable you to trade stocks and crypto directly from the timeline,” he added.

The statements follow Bier’s earlier comment on a post by Argentine tech entrepreneur Santiago Siri about Peter Steinberger, the mind behind Clawdbot, now OpenClaw.

Siri argued that Steinberger’s claims of losing up to $20,000 per month clash with his public disapproval of crypto enthusiasts attempting to tokenize his projects, suggesting he may be overlooking substantial potential fees.

Bier called Siri’s perspective “the most dishonest” he’d seen, stressing that apps collecting fees from non-consenting users would backfire.

The X product chief said X is updating API rules to prevent such apps, aiming to foster crypto innovation without harming the user experience.

Frankly, this is the most dishonest perspective on the “claim your fees” spam that I’ve ever read.

Everyone knows that the moment he does it, it will haunt him on for the rest of his tenure on this app. Every reply will be about making the price goes up.

We intend to update…
