President Donald Trump's cryptocurrency, called $Trump, has cost investors billions. Trump announced the launch of his meme coin"a type of cryptocurrency that features Internet memes or celebrity mascots"just three days before his inauguration. "Join my very special Trump Community. GET YOUR $TRUMP NOW," he wrote on TruthSocial. The opening sale for one of the 5,971,750 tokens was just 18 cents, but it quickly surged to $75. But the price of $Trump has since plummeted to about $17.
