Bitcoin, 沒有任何內在價值（不像黃金），也沒有實際用途（以太幣支持各種去中心化應用和項目，在交易上比bitcoin方便得多，快得多）。Bitcoin值多少錢，在於人類的sentiment。 一旦這個sentiment失效，它的價格就會迅速下降（可以是0）。
Bitcoin和stable coin不同的地方在於，bitcoin的價值不與美元對接，也沒有黃金儲存作為擔保。一旦市場被trigged a sell off, 它沒有任何底線。
但是，目前bitcoin的價值有以下五個方麵作為保障：
- Institutional Adoption As institutional investors like banks, hedge funds, and publicly traded companies integrate Bitcoin into their portfolios, it reinforces trust and long-term stability. Institutional adoption adds liquidity to the market and signals confidence to smaller investors, reducing the likelihood of a complete price collapse.
- Decentralized Network Security Bitcoin’s blockchain is maintained by a global network of miners, ensuring it is nearly immune to centralized failures or attacks. This decentralization makes Bitcoin highly secure, giving users confidence in its continued functionality and preventing large-scale abandonment.
- Limited Supply (21 Million Cap) Bitcoin’s hard cap of 21 million coins creates digital scarcity, similar to precious metals like gold. This scarcity is a key driver of its value and prevents inflationary devaluation, which is common with fiat currencies. The fixed supply makes it unlikely to lose all value, even during market downturns.
- Global Investor Base Bitcoin’s adoption spans across borders, with millions of individuals, businesses, and institutions investing worldwide. This global demand ensures that Bitcoin remains valuable in diverse economic conditions, reducing the risk of a complete market collapse.
- Utility in Transactions Beyond investment, Bitcoin serves as a payment method for cross-border transactions and a hedge against inflation in some economies. Its utility creates ongoing demand, making it more than just a speculative asset and less likely to lose all value.
