| Transaction Type | Tax Treatment | Coinbase Reporting (US) |
|---|---|---|
| Buying USDC with USD | Not a taxable event | No form issued for the purchase itself |
| Earning USDC rewards/interest/staking | Taxed as ordinary income at fair market value when received | Form 1099-MISC if you earn $600+ in a year |
| Selling USDC for USD | Taxed as a capital gain or loss. The gain/loss is generally zero due to the 1:1 peg, but it must still be reported | Form 1099-DA (starting for tax year 2025) |
盈利不在coinbase，coinbase的gain应该算是0；冻卡应该是收到黑钱了，出金可能遇到，入金几乎不可能
