Bitcoin ($BTC ) remains the top cryptocurrency by market capitalization and is gaining recognition as a store of value in many countries. Institutional investments have contributed to its price stability to some extent, but transaction fees and processing times have increased. Additionally, its high energy consumption and market volatility continue to pose challenges for investors.

Ethereum ($ETH ) has transitioned to the Proof of Stake (PoS) model with the Ethereum 2.0 upgrade, making transactions faster and more eco-friendly. It continues to dominate the NFT and DeFi ecosystems, but high transaction fees remain a concern for users.
