#BTCvsETH

* Purpose: Bitcoin functions as "digital gold" and is a means of storing value with a limited supply. Ethereum is a programmable platform for smart contracts and decentralized applications (dApps).

* Consensus mechanism: Bitcoin uses Proof-of-Work (PoW), which provides high security and decentralization, but is energy-intensive. Ethereum has transitioned to Proof-of-Stake (PoS) with Ethereum 2.0, which reduces energy consumption and improves scalability.

* Economic model: Bitcoin has a hard cap of 21 million BTC. Ethereum does not have a fixed limit, but burns a portion of the fees, which can lead to deflation.
