How does EIP-1559 change Ethereum fees?

EIP-1559 introduced a base fee (burned) plus priority tip (to validators). Base fee adjusts algorithmically based on demand. Users pay base + tip; base is burned, removing ETH from supply. Tips go to validators.

Why do Bitcoin fees spike?

Bitcoin blocks have limited space (~1MB equivalent). When many transactions compete for block inclusion, miners select highest fee transactions. Fee spikes occur during bull markets, Ordinals inscriptions, and BRC-20 token activity.
