A group of crypto traders reportedly purchased millions of dollars worth of Melania Trump’s memecoins minutes before she announced the launch on social media.

According to a May 6 Financial Times report, the crypto traders earned roughly $100 million from buying $2.6 million worth of MELANIA tokens before the public launch on Jan. 19. Shortly after Trump announced the memecoin launch on social media, the price surged from roughly $2.00 to $12.95 — a 550% increase. The traders reportedly sold their holdings within 12 hours.

“In total, the 24 accounts bought up 16.7mn of the 200mn total $MELANIA tokens scheduled for sale during the launch period,” the Financial Times reported. “[…] the run of sales that started pre-launch continued. About $900,000 worth of tokens bought by an additional 22 accounts in the 42 seconds after the launch.”

The memecoin started trading roughly two days after then-president-elect Donald Trump announced the launch of his own TRUMP coin. Both tokens have come under scrutiny from lawmakers, alleging conflicts of interest and corruption due to the potential for bribery and foreign influence.

Memecoin dinner prompts call for impeachment

Much of the scrutiny and criticism from US lawmakers over the memecoins seems to be directed at the president rather than the first lady. After Trump announced some of the top TRUMP tokenholders would be offeried the chance to get access to him at a private dinner and tour, one senator called for his impeachment.

Both the prices of the MELANIA and TRUMP tokens have dropped significantly since shortly after their launch in January, with the First Lady’s memecoin falling to $0.31 at the time of publication. The TRUMP token price briefly surged after the memecoin dinner announcement in April, but had dropped to $10.90 as of May 6.

Two companies connected to the president control roughly 80% of the TRUMP supply, though many of the tokens were locked and will be released over the next three years. Critics have suggested that the project’s insiders could still rug-pull investors.
