Over the past two weeks, our team XDO has been working closely with @worldlibertyfi — and honestly, it’s been a real surprise for me. 最近两周，我们团队XDO开始和 @worldlibertyfi 密切合作，狠狠的教育了我！ Tbh, I had my own stereotypes at the beginning. Trump-backing, access to top-tier global resources — I assumed the team would be the type like: big vision, endless resources, everyone coming to them instead of the other way around. I mean, you can easily afford to be a “laid-back” team with this level of privilege and prestige.😂 说实话，刚开始接触的时候我是有刻板印象的。总统家族背景，全球顶流资源，我assume团体风格会是：愿景很大、资源很多，一定是所有的资源去找他们。可以猜想这种有顶级资源的美国团队有多么躺。 But after two weeks of working with them, I was genuinely impressed — even humbled. 但接触下来非常惊喜，甚至教育到我。 On nye, co-founder @ZachWitkoff was still handling interviews job. By Jan 2nd — when most people were still in holiday mode — their entire team was fully back in action. Every sync was well-prepared, execution was fast, and nothing was half-hearted. Even though many team members didn’t come from a Web3 background, everyone was actively and intensely learning. In every discussion, they consistently identified the single most critical key to success, made fast decisions, and mobilized the entire team to execute. From @ZachWitkoff & @zakfolkman founding-team-level market strategy decisions to execution, implementation, and even contract reviews — all of that can happen within a single day. 新年当天，Co-founder @ZachWitkoff 还在处理这面试的工作。1月2号，当大多数人还在休假模式的时候，他们已经全员到岗火力全开了。每次对接，准备充分，执行迅速，一点不含糊。虽然，很多人之前没有Web3背景，但是每个人在饥渴的学习Web3的知识。并且每次探讨中，总是可以找到决定事情成功的最核心的KEY，然后快速决策并全团队响应执行。是的，从大市场战略的Founding team决策到对其执行到落地执行包括审核合同，一天足以。 This made me reflect: why is a team with such a background working even harder than many startup founders? 这让我开始反思：为什么有这种背景的团队，反而比很多一般的创业者还拼？ My guess? Because the whole world is watching. If a normal project fails, you pivot and start over. But WLFI is different — with this kind of background, success is expected. That expectation pushes the founding team to focus on how to succeed even more. That pressure forces them to put in 200% effort to prove that what they build goes far beyond what their so-called “background” could ever hand them. 我猜的——因为全世界都在看。普通项目失败了，换个赛道重来就是。但 WLFI 不一样，顶着这种背景，成功变成了是应该的。所以，整个创始团队更聚焦在如何可以更加成功！这种压力，逼着他们必须用 200% 的努力去证明自己可以做的事情要远远超过他们“所谓的背景”可以给予的。 Another detail I noticed: their execution logic is extremely clear. It’s not the “we have resources, let’s just throw money at it” mindset. They are deliberately building long-term value step by step. They value every partner and every dollar — while also knowing how to turn those into weapons for rapid market capture. And when it comes to critical decisions, they don’t hesitate to invest heavily. You can imagine what this combination can ultimately become: top-tier resources + top-tier execution + a massive market = Massive future for @worldlibertyfi $USD1 By the way, this also validates a thesis I shared in my previous article (link below): in 2025, stablecoins are increasingly becoming the bridge to mainstream assets. Sustainability at the business level matters — and this is exactly the direction we’ve been betting on. 而且我观察到一个细节：他们团队做事的逻辑非常清晰，不是那种「有资源就随便造」的心态，而是真的在一步步构建长期价值。珍惜每一个合作伙伴，珍惜每一分钱，但是同时这些也可以成为快速抢占市场的武器。对于关键事情上，丝毫不吝惜。我们可以想象这种组合——顶级资源 + 顶级执行力 + 超级大的市场 WLFI USD1可以成为什么样最终形态。顺便说一句，也验证了我在之前一篇长文里的思考，今年稳定币成为连接主流资产的趋势越来越明显了。业务本身的可持续性。这也是我们一直在押注的方向。 So YEP! My view on WLFI has completely changed. This is a team that genuinely takes execution seriously, and have the power to make all dreams come true. 所以我现在对 WLFI 的看法彻底改变了。至少从合作体验来说，这是一个认真做事并且有实现造梦能力的团队。 If people with backgrounds are working this hard, what excuse do those without one have to be laid-back?? 「Don't make excuses for not being where you want to be. It usually comes down to not trying hard enough, or focusing on the wrong things.」 「Jiayi never used to create anxiety. But from now on, anxiety and self-reflection start with Jiayi.」 有背景的人都在拼命，没背景的凭什么躺平？ 「不要给自己的不够优秀找借口。大多数就是自己不够努力，或者努力方向不对！」 「Jiayi之前不制造焦虑。但是从现在开始，焦虑和反思从Jiayi开始。」 Side note: after deeply engaging with the founding team, I started allocating heavily into $ALTS (already 100% in profit so far) and $WLFI. I’m happy to say that so far, the results have been very encouraging. 题外话： 正式因为深度的接触了创始团队后。我开始重仓WLFI的DAT股票 $ALTS (且翻倍了）和 $WLFI。很开心，目前为止，让我看到了好的结果。 LONG Crypto 🚀 LONG Stablecoin 🚀 LONG Myself

crypto这个行业离钱太近，做一家公司长则10年以上，短则也要3～5年才能上市，创始团队们要不停的思考商业模式和盈利增长。 而在crypto,一年不到就能登陆交易所，项目所谓的叙事只是快速去通过代币激励来催熟数据，制造虚假繁荣，然后在顶点套现。 巴菲特说：When companies with outstanding businesses and comfortable financial positions find their shares selling in the market at prices far below intrinsic value, no alternative action can benefit shareholders as surely as repurchases. 这句话也不难理解，购买公司股票的最后只能是公司自己。优秀的企业会在自己被低估时选择回购，而在crypto几乎绝大多数项目从不回购（项目本身甚至不产生利润），即使回购也是为了更好的套现。 HYPE的成功很多人归咎于所谓的避税，所谓的监管套利，甚至洗钱。我觉得都不对，前人想过无数路子来绕开这些，而真正成功的只有HYPE。业内人士避而不谈创始团队拥有的宝贵品质，以及当写下要打造链上金融系统的雄心，因为大家默认减持，下跌会发生。 回过头来，我作为普通的投资者，审视一家公司，一个项目，问的第一个问题永远会是：到底谁在买入他们的股票/或者代币？
