Summary
TLDR: If Bitcoin had no fees like Solana, there would be chaos with spam transactions causing delays. Solana struggles with dropped transactions due to bots flooding the network. Developers are working on solutions like implementing priority fees and a new version of Solana to address these issues. Arbitrage bots are causing problems on Solana, and a fee model overhaul may be needed in the future.
Key Points
1. If Bitcoin were completely free to use, there would be mayhem not unlike the troubles that Solana currently faces.
2. No fees would clog Bitcoin’s mempool with useless mini-transfers, causing extended delays and potential for transactions to be ignored altogether.
3. Bitcoin’s fee auction model prices out potential spam attacks, making most kinds of spam economically unfeasible and leaving more room for legitimate activity.
