Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesOur effective tax rate was 22% and 31% for the six months ended June 30, 2022 and 2021, respectively, and 23% and 35% during the three months ended June 30, 2022 and 2021, respectively. The effective tax rates for the six months and three months ended June 30, 2022 were lower than the effective tax rates for the comparable periods in 2021 primarily due to the deferred income tax impact from U.K. tax law changes as well as from the impact of the sale of our investment in Coinbase during the six months ended June 30, 2021. During the three months ended June 30, 2021, the U.K. Finance Act 2021 was enacted, which increased the U.K. corporate income tax rate from 19% to 25%, effective April 1, 2023. The combined impact of the U.K. deferred tax provision and the sale of our investment in Coinbase for the six months and three months ended June 30, 2021 increased our effective tax rate by 8 and 12 percentage points, respectively.
