1． 稳定币的本质：价格锚定 → 稳定币，听起来像是币圈的"定存"？其实它更像是超市储值卡。 你有没有买过超市的100块储值卡？哪怕你半年后才刷，它也还是值100块。稳定币的道理差不多：它的 价格始终锚定在1美元上下，不管市场如何波动，大家都信它值1美元。就拿现今占市场份额超过90%的 USDT和USDC两家币种来说，他们的稳定币都是与美元1：1进行兑换的。 Q：为什么稳定币能维持"1美元"？ （锚定机制：通过真实资产储备或算法调控，确保稳定币价格稳定在目标值附近的制度设计。） 比如价格跌到0.98美元，套利者会低价买入，再去官方换回1美元，中间赚2分钱。正是这些套利操作在 帮市场自动修正价格。 2． 三种抵押方式与代表项目 → 虽然表面上都长得像"1美元"，背后的做法其实各不相同。 稳定币的生成方式分为三种，就像房子有钢筋混凝土的，也有木结构的，还有搭积木的，每种结构各有 利弊。 | 低押方 ERSESSMENTS SESSEDS SECREED TREESS CORRESS SECTION CONSULTED | 代表项目 | | 风险点 | | --- | --- | --- | --- | | 法币抵 ...

Core Insights - In April 2025, international gold prices surpassed $3,500 per ounce, marking a historical high, while Hong Kong experienced a contrasting surge in gold sell-offs, indicating a significant divergence in market sentiment between Hong Kong and mainland China [1][2]. Group 1: Market Dynamics - The sell-off in Hong Kong is driven by rational investment strategies rather than mere profit-taking, highlighting a complex interplay of market emotions and rationality [4]. - In contrast, the mainland market is characterized by irrational behaviors, such as leveraging and extreme buying, driven by traditional beliefs and social media influences [5]. Group 2: Arbitrage and Investment Behavior - Hong Kong institutional investors engage in arbitrage by capitalizing on price discrepancies between markets, achieving profit margins of up to 5% through strategic purchases [7]. - Hong Kong investors exhibit heightened sensitivity to gold's cyclical fluctuations, influenced by recent market volatility and a shift towards lower-risk assets like high-dividend stocks [7]. Group 3: Policy and Cost Considerations - The lower transaction costs in Hong Kong, with trading commissions as low as 2% and no value-added tax, encourage short-term trading strategies compared to the higher costs faced by mainland investors [7]. Group 4: Investor Psychology and Risk Management - The contrasting views on gold reflect a generational gap in investment philosophy, with Hong Kong viewing gold as a quantifiable financial tool, while mainland investors often see it as a means of wealth preservation [11]. - Risk management practices differ significantly, with Hong Kong institutions maintaining strict position limits, whereas some mainland investors engage in high-leverage strategies that expose them to substantial risks [11].
