泰達幣（Tether），簡稱USDT，是一種加密貨幣穩定幣，由Bitfinex交易平台的母公司iFinex Inc.發行。作為一種穩定幣，泰達幣的設計初衷是與傳統法定貨幣（如美元）等價，以穩定價格，便於數字貨幣交易者在市場波動時進行價值儲存和交易。泰達幣的特點在於其錨定性，即每個泰達幣代幣都宣稱以1美元的價值為基礎。這種錨定使得泰達幣在交易時可以充當數字代幣和美元之間的橋樑，使交易者能夠在數字貨幣市場中獲得一定程度的價格穩定性。泰達幣的運作機制基於兩個關鍵原則：儲備金和發行與銷毀。發行新的泰達幣通常需要與等值的美元進行兌換，而用戶在進行泰達幣的銷毀時可以將其兌換回美元。這一機制保證了泰達幣的價值與美元保持1:1的穩定比例。儘管泰達幣被設計為具有穩定性，但它並不是完全沒有風險。首先，穩定幣領域一直受到監管審查和法律規定的影響。其次，如果泰達幣發行者無法兌現持有者的代幣，可能會引發信任危機。儘管泰達幣的發行者聲稱其代幣是以等值的儲備資金支持的，但這種聲稱並未得到全面的獨立審計。儘管如此，泰達幣在數字貨幣交易市場中廣受歡迎。它在加密貨幣交易中充當了一個流行的交易對，允許交易者在市場波動時將資金錨定到穩定的價值上。這為交易者提供了一種規避市場波動的方式，尤其是在不願意持有較大風險的情況下。總之，泰達幣是加密貨幣領域中的一種穩定幣，旨在通過與法定貨幣等值的錨定機制提供價格穩定性。儘管存在一些監管和風險問題，但泰達幣在數字貨幣交易者中廣受歡迎，為他們提供了在市場波動時進行交易和價值儲存的選擇。隨著加密貨幣市場的不斷發展，泰達幣將繼續引起人們的關注，並在數字貨幣生態系統中發揮重要作用。
