Famous tech entrepreneur Elon Musk has resorted to emoji in an apparent brief online spat with prominent investor Peter Schiff.

The exchange started when Schiff tweeted about how, two weeks after Musk “announced that he spent $1.5 billion of shareholder money buying Bitcoin”, Tesla stock plummeted, with the investor adding that it is “not an example other CEOs will likely follow”.

In response, Musk simply tweeted an eggplant emoji, with many social media users appearing both amused by Elon’s response and eager to elaborate on what exactly he wanted to say.

Schiff himself also did not sit idly by, responding that he “would have expected a more thoughtful reply” from Musk, eliciting a fresh barrage of mockery from social media audience.
