Regarding the possibility that ALT cryptocurrencies may surpass Bitcoin and become the dominant currency in the next 60 years at most, it mainly focuses on several key factors:

$ALT $BTC $ETH

Technological innovation: As blockchain technology develops, new cryptocurrencies (such as ALT) may introduce more advanced features and improvements, which may attract more users and developers. For example, Ethereum has attracted attention for its smart contract function, which Bitcoin does not have1.

Market adaptability: Emerging cryptocurrencies may be more flexible to adapt to market changes and user needs, thereby gaining an advantage over the competition. Although Bitcoin is the first widely accepted cryptocurrency, some of its design decisions (such as non-programmability) may limit its long-term market potential1.

Network effect: The value of a cryptocurrency depends largely on the size and activity of its network. If ALT can build a strong user and developer community, it may gradually surpass Bitcoin's network effect.

Regulatory environment: Different countries and regions have different regulatory attitudes towards cryptocurrencies, which may affect the development of various cryptocurrencies. Some new cryptocurrencies may better adapt to regulatory requirements and thus gain wider acceptance.

Economic model: The supply and demand mechanism of a cryptocurrency has a significant impact on its value. For example, an ALT may adopt an economic model different from Bitcoin, which may attract investors seeking to diversify their portfolios2.
