Cryptocurrency fans may have gotten more than they bargained for when the president and his wife launched a pair of tokens last week.

Just before assuming office as the 47th president of the United States, Donald Trump introduced his meme coin – $Trump. The digital token attracted lots of attention, and a couple of days after its launch the combined value of the coins was nearly US$8.5 billion (£6.9 billion).

Just days ahead of his return to the White House, President Trump and his wife, Melania, launched a pair of meme coins that have skyrocketed in value and earned them billions of dollars, at least on paper.
