多地发布风险提示—— 防范披着“稳定币”马甲的骗局
Jing Ji Ri Bao· 2025-07-26 22:26
7月以来,多地金融管理部门、行业自律组织等接连发布风险警示公告提示,随着稳定币概念的升温, 一些不法分子以稳定币为噱头进行的非法活动有所冒头,其潜在风险值得高度警惕。 要避免上当受骗,首先需要搞明白什么是稳定币。稳定币是一种锚定真实资产的数字货币,其价值通常 与某种法定货币、商品或其他资产挂钩。不少投资者表示困惑:"既然都是加密货币,那稳定币跟之前 很火的比特币一样吗?"答案是否定的。 上海金融与发展实验室主任曾刚介绍,二者的主要区别体现在价值锚定机制、价格波动性、应用场景等 方面。其一,价值锚定机制不同。稳定币通常与法定货币或其他稳定资产挂钩,1枚稳定币的价值等同 于1单位锚定资产,从而保持价格稳定;而比特币属于"原生加密货币",其价值完全取决于市场供需, 没有任何实物或法币资产作为支撑,因此波动性极大。 其二,价格波动性区别明显。稳定币旨在抑制波动,适合作为价值存储和交易媒介;比特币则追求"去 中心化的数字黄金"定位,价格受市场情绪、宏观经济和政策消息驱动,涨跌幅度剧烈。此外,应用场 景亦有差异。稳定币常用于数字资产交易的计价、资金结算、跨境转账等场景;比特币则被视为长期投 资或价值储备工具。 中国邮政储 ...
