## Reach
- followers: 316238
- following: 4515
- posts_total: 22070
- posts_observed: 7
- posts_per_day: 11.272
- account_age_days: 1958

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0.00009
- best_post_interactions: 30
- measurement_source: x_post_interactions
- measurement_formula: interactions on one post — likes, or likes + reposts + replies depending on the discovery path (the two are not distinguishable in the stored data)
- comparable_pool: peak_interactions
- status_note: We have only the single best observed post, so no mean exists. peak_post_engagement_rate is an UPPER BOUND, systematically higher than an average — never compare it against an average rate.
- unit_note: engagement_rate and peak_post_engagement_rate are ratios (0-1); avg_interactions_per_post and best_post_interactions are absolute counts. Read status before reading any number: a null rate has several different causes and status says which one applies here.

## Evidence
- [x_btcdayu#ed68737a] 加密收税、多国穿透收税是是大势所趋，不用讨论会不会，只需要讨论何时。 25年起，接到海外投资征税的通知的人数激增； 26年，海外信托直接打穿，每年扣税20%之类相当令人震惊。 与中国高净值人群相关的香港、新加城、开曼等，全部加入，收税没问题，但担心像股票一样只算盈利，亏损不抵税。 https://t.co/R8Jvt7p0DW (https://twitter.com/BTCdayu/status/2043310265824059491)
- [x_btcdayu#7386a22c] 综合税收和居住体验来说，现在香港可能是全世界最好的城市。 当然，唯一的问题就是存在某些无法预知的风险。
- [x_btcdayu#8f52069c] 傲娇的Nikita离开了。 我记得刚来推特的时候，其实好像感觉每天都有非常多精彩的、深度的东西可以看。 但现在好像时间线上全是各种搬运的、想办法博眼球的东西。
- [x_btcdayu#c2a20c81] 香港这边的大学真的很不错 尤其是这个0xu，真是人才济济 多希望我现在也是23岁才上大一
- [x_btcdayu#0d829d6a] 大模型的核心竞争力不是看谁领先，都是暂时的 下一步，看谁是自己有芯片，能源，专家，渠道等全栈的，这样就有成本优势，分发优势，这样的话，spacex和google会很牛。
- [x_btcdayu#9e728225] 绅士们，如果必须且只能选一个，她将成为你的女友一天。 你选谁？ https://t.co/tSK5oaYL8N
- [x_btcdayu#c718d809] 有一个说法是，明年差不多，包括币安在内，所有的交易所要向中国政府提交信息，也就是CRS2.0会对加密货币持有者收税。 如果像股票一样，亏损的不抵税，赚钱都要收税的话，基本上可能要倒贴。 届时不需KYC的链上去中心化交易所会很重要。
