Kamala Harris is considering imposing a 25% unrealized capital gains tax, which could seriously weaken the long-term holding power of bitcoin investors. Latest reports indicate that Vice President Kamala Harris is endorsing Joe Biden's FY 2025 budget proposal, which would impose a capital gains tax of up to 45 percent on long-term investments in the United States. If that wasn't enough, she's also considering a 25 percent tax on unrealized gains. If implemented, this could seriously hurt long-term bitcoin investors and could even force cryptocurrency companies to eventually pull out of the United States.
