Bitcoin differs from the other cryptocurrencies because Bitcoin is the only one that is truly decentralized and secure. While others may advertise themselves as being “faster” or “better” than Bitcoin, they sacrifice either security or decentralization in the process.
Furthermore, these other coins do not utilize a proof-of-work timestamping scheme.
Bitcoin’s use of proof-of-work timestamping creates a link to the physical world, where physical world resources (electricity) and time are needed to mine blocks and secure the network.
Finally, Bitcoin is money and focuses on being it, while the rest are not. They are centralized scams.
