实用结论

本文最有价值的地方是克制。账户历史导出是证据工具,不是可以互换的 CSV 文件。Coinbase 说明,用户可下载既有月度 statement,格式包括 HTML、PDF 或 CSV,也可按资产、交易类型和日期生成自定义 statement,并通过 Coinbase Taxes 使用 gain/loss 或税务报告。Kraken 说明,导出请求可覆盖 Account Statement、Trades、Ledgers 和 Balances,可下载 CSV 或 PDF,并且处理时间可能从几分钟到一周不等,准备好后目前不会发送邮件通知。NexuAlpha 的雷达结论是,可靠归档必须先写明平台、报告类型、日期范围、资产范围、处理延迟、文件格式、留存限制和对账目标,再用于税务、审计、支持或恢复决策。 用户应获得一个更清楚的核验路径,而不是一个看似肯定、实则无法由公开证据承担的承诺。
