All cryptocurrencies are not the same because they have different features, uses, and underlying technology. Some of the factors that make them different include:
Blockchain technology: Different cryptocurrencies use different types of blockchain technology. For example, Bitcoin uses a proof-of-work consensus mechanism, while Ethereum uses a proof-of-stake consensus mechanism.
Purpose and use case: Some cryptocurrencies, like Bitcoin, were created primarily as a digital currency for peer-to-peer transactions. Others, like Ethereum, were created to support decentralized applications and smart contracts.
Supply: The total supply of different cryptocurrencies can vary greatly. For example, Bitcoin has a fixed maximum supply of 21 million coins, while other cryptocurrencies have a much larger supply or even infinite supply.
Transactions per second: The number of transactions that can be processed per second varies greatly among different cryptocurrencies. For instance, Bitcoin can process around 7 transactions per second while Ethereum can process around 15 transactions per second.
Privacy: Some cryptocurrencies are more private than others. For example, Monero is known for its strong privacy features, while Bitcoin transactions can be traced back to their origin.
Governance: Some cryptocurrencies have a decentralized governance structure, with decisions made by the community, while others have a more centralized governance structure with a small group of developers making decisions.
All these factors combined make each cryptocurrency unique and create different use cases, values and behaviours.
