[Mark]

The key difference between Bitcoin and Ethereum lies in the functions they serve.

Bitcoin's main purpose is to be a secure, decentralized digital currency for transactions. Ethereum, on the other hand, lets people build decentralized apps. People perceive Bitcoin as more valuable because of its limited supply and security, akin to 'digital gold'. Ethereum focuses on being programmable, with a flexible supply.
