1. Use as Real Money: Bitcoin has been accepted as a form of payment by various businesses and online platforms. Its decentralized nature allows for peer-to-peer transactions without the need for an intermediary, fitting the fundamental attributes of money. However, its acceptance is still not widespread, and volatility in value can be a barrier to regular usage. 2. Speculation vs Foundation: Bitcoin has a foundational basis in its underlying technology, the blockchain, and its limited supply (21 million coins). But the price can be highly speculative, driven by investor sentiment and market dynamics. 3. Hype Factor: The belief that Bitcoin is the "next big thing" varies among individuals and institutions. There is certainly a hype component in the market, often amplified by media and market influencers. However, Bitcoin's resilience and growth since its inception in 2009 provide evidence of underlying substance beyond the hype. 4. Scalability and Failure Claims: Scalability has been an issue with Bitcoin, particularly with the limitations in the number of transactions that can be processed per second on the main chain. Solutions like the Lightning Network are attempts to address this, but scalability remains a challenge. Claims of failure are often tied to regulatory, environmental, or technical concerns but must be balanced with ongoing developments and the continued interest from institutional investors.
