Giải thích về đường trung bình động: Đường trung bình động là đường nối giá trung bình trong một khoảng thời gian, dùng để làm mượt biến động giá và xác định hướng xu hướng. Giá nằm trên đường trung bình thường là xu hướng tăng, nằm dưới là xu hướng giảm. Đường trung bình ngắn hạn cắt lên trên đường trung bình dài hạn là giao cắt vàng (tăng giá), cắt xuống dưới là giao cắt tử thần (giảm giá). Sắp xếp tăng giá (ngắn hạn > trung hạn > dài hạn) cho thấy xu hướng tăng mạnh, sắp xếp giảm giá thì ngược lại.
Polygon Bridged USDC (Polygon PoS) (USDC.E) Câu hỏi thường gặp
USDC.e is a bridged version of USDC, originating on the Ethereum blockchain and transferred to Polygon PoS via a third-party bridge. It is not directly issued by Circle. Native USDC on Polygon PoS, launched by Circle on October 10, 2023, is directly issued and fully backed by Circle on the Polygon network. The key difference lies in their origin and issuer; USDC.e relies on the bridge's security, while native USDC is directly supported and managed by Circle.
While generally functional, USDC.e carries a higher inherent risk compared to native USDC. Its security relies heavily on the integrity and trustworthiness of the third-party bridge operators used to transfer it from Ethereum. Should such a bridge be compromised or suffer an exploit, there is a potential risk of loss of backing for USDC.e. Native USDC, being directly issued by Circle, bypasses this additional layer of risk associated with a third-party bridge.
No, USDC.e is not directly supported by Circle for redemption. This means users cannot convert USDC.e into US dollars using Circle's official platform or services. In contrast, native USDC on Polygon PoS is fully and directly redeemable 1:1 for US dollars via Circle's official platforms, offering a direct conversion path and stronger assurance of its backing. This distinction is crucial for institutional users and those seeking direct fiat off-ramps.
The launch of native USDC by Circle on Polygon PoS on October 10, 2023, marks a significant transition from the older bridged USDC. This migration aims to simplify transactions, enhance liquidity across the network, and improve the overall user experience. By having a directly issued and supported version of USDC, the Polygon ecosystem gains a more robust and streamlined stablecoin, fostering greater trust and integration with Circle's services and broader financial systems.
While existing USDC.e balances remain usable on some platforms, users are strongly encouraged to transition to native USDC. Circle discontinued support for deposits and withdrawals of USDC.e for its Circle Account and APIs on November 10, 2023. Users utilizing these services should swap their USDC.e to native USDC to avoid potential issues. Many decentralized finance protocols and marketplaces are also advising or requiring this transition for full functionality and future compatibility.
