' D% [: D2 K4 p% n; { v8 h% t穩定幣有很多種類，比較常見的有：法幣穩定幣(Fiat-backed Stablecoin)、數字資產抵押穩定幣(Crypto-backed Stablecoin)、 商品穩定幣(Commodity Stablecoin) 和演算法穩定幣(Algorithmic Stablecoin)。; v0 d4 F/ t7 S7 w; e5 Z# }
. D& x6 X. h3 A9 q7 \
以法幣作擔保的穩定幣 (Fiat-backed Stablecoin) 這是最常見，也最受歡迎的一種穩定幣類型，與法定貨幣1:1錨定。
* O! H {: H1 g4 @- w5 }+ ]代表1個穩定幣等於1個法幣（例如1美元 = 1 USDT），每個穩定幣背後，都有真實的法幣作為擔保儲備金被存放在銀行裡。可以說投資人手上有多少價值的穩定幣，銀行賬戶裡就有多少相應價值的法幣資產作為“儲備金”。
8 ~8 u3 L* q# }比如投資人用 1 法幣購買 1個穩定幣，發行方會將 1 法幣作為儲備金存放在銀行賬戶裡。
, R6 G6 _" L2 S! I4 c而當投資人想將1 法幣兌換回來時，發行方會將1法幣兌換給投資人，然後收回並銷毀這1個穩定幣。 0 q& a( Q4 s* b
這很容易理解，對於新手來說持有穩定幣和現實世界的法幣沒什麼區別，因此穩定幣也經常作為虛擬貨幣世界的敲門轉。 5 _: T r& d2 h* K- R
只要發行穩定幣的公司確保1:1錨定法幣，並且有足夠的“儲備金”做擔保，原則上穩定幣的價值都不會發生太大波動。
) ~; p* D) X" O0 Q F比較有代表性的法幣穩定幣有：USDT（Tether/泰達幣）、USDC（USD Coin），這兩種代幣與美元1:1錨定，基本佔據穩定幣70%的市場，但圍繞他們現金儲備不夠的爭議一直存在。最近發展很快的BUSD（Binance USD），同樣是錨定美元的穩定幣，財務以及美元儲備都更透明。 $ c i" E& w- v) k2 C# C
也有其他法幣支持的穩定幣，如：XSGD由新加坡元1:1支持，歐洲 Stasis的 EURS代幣1:1錨定歐元等等。 7 H4 [) \4 \- @' b/ s+ A- d. v
