Memecoins have long traded in crypto markets, with Dogecoin perhaps the best-known example. Launched as a joke, the crypto has exploded in popularity over the years, with its price often riding on the whims of its backers — the best known of which is Elon Musk.

President-elect Trump has launched his own crypto token called Trump coin. In less than 24 hours, the coin has had a 12,000% gain and has seen billions in trading volume.

In the days leading up to President Trump's inauguration, he and his family launched a new memecoin, much to the concern of some in the crypto industry.
