Donald Trump and his wife Melania’s new memecoins ignited criticism from crypto executives who were expecting the digital-asset sector to be treated seriously by the Republican’s incoming US administration.

The president-elect unveiled the “Trump” token on Friday and his wife Melania launched her “Melania” effort on Sunday. The Trump memecoin’s market value hit $15 billion at one point but then briefly slid below $8 billion as Melania’s token took some of the spotlight, figures from aggregator CoinMarketCap show.
