所有加密貨幣的供應量都有限嗎？ [。 以下是用提問者的語氣進行的描述，字數不超過300： 「嘿，我已經聽說了很多關於加密貨幣及其獨特特徵的內容。不斷出現的一件事是有限供應的概念。所以，我的問題是，所有加密貨幣的供應都是有限的嗎？我知道有些，像比特幣一樣，可以開采的硬幣數量是有限的，但是這條規則是否適用於所有加密貨幣？貨幣的價值和穩定性。

Certainly! Here's a description in the tone of a questioner, with a word count of no more than 300: "Hey there, I've been hearing a lot about cryptocurrencies and their unique characteristics. One thing that keeps popping up is the concept of limited supply. So, my question is, does all crypto have a limited supply? I understand that some, like Bitcoin, have a finite number of coins that can ever be mined. But does this rule apply to all cryptocurrencies? Are there any exceptions to this rule? I'd love to hear your thoughts on this topic and understand the implications of limited supply on the value and stability of various cryptos.
