Are all Cryptos the same?

Are all cryptocurrencies truly identical, or do they each possess unique qualities and characteristics? Is there a standardized blueprint that all digital assets adhere to, or do they vary widely in terms of their technology, purpose, and potential? As an investor or user, should I assume that any cryptocurrency will offer the same experiences and opportunities, or is it crucial to research and understand the differences between them? Are there any key factors I should consider when evaluating the distinctiveness of a cryptocurrency, such as its underlying blockchain technology, tokenomics, or use case?
