Trump had previously called cryptocurrencies a “scam” but during the 2024 election campaign he became the first presidential candidate to accept digital assets as donations.
During his election campaign, Trump also said he would create a strategic stockpile of Bitcoin and appoint financial regulators who would take a more positive stance toward the digital asset.
This has prompted expectations that he will eliminate regulations related to the cryptocurrency industry.
In the wake of Trump's victory, bitcoin jumped to a record high and is currently trading at $140,000, according to cryptocurrency trading platform Coinbase.
