In the 2020 U.S. presidential election, the campaigns of the two major candidates (incumbent President Trump and President Biden) cost billions of dollars. For example, Biden's campaign expenses exceeded $1 billion, and Trump's spending was close to the same amount.
It's not yet known how much will be spent on this year's presidential campaign, but Donald Trump raised $25 million at the 2024 Bitcoin conference, marking the second highest amount raised in his three presidential campaigns.
