Small-amount exemption + special handling for stablecoins + wash sale + validator rewards + safe harbor, five-pronged approach, can be considered a systematic legislative revision.

Crypto World News: U.S. bipartisan lawmakers have reintroduced the "Digital Asset Protection, Accountability, Regulation, Innovation, Taxation, and Revenue Act" (Parity Act), a cryptocurrency tax reform bill aimed at updating digital asset tax rules and requiring the IRS to study the applicability and potential impact of tax exemptions for "small digital asset transactions." The bill proposes that compliant payments with stablecoins, when the cost basis is less than 99% of the redemption value, should not be counted as gains or losses, and also involves digital asset wash sale rules, validator income tax treatment, and safe harbor provisions for broker and taxpayer account transactions. The bill also requires the IRS to assess the tax burden of small crypto transactions under $200 under current law and the potential abuse risks of related exemptions.
