Why are Bitcoin miners not speeding up and expediting the confirmations? Is it for personal gain? in that case that means Bitcoin is centralized and not decentralized because miners can control its fees?
There's no need to twist it around into centralized vs decentralized debate, especially if how miners work is not clearly understood. If you want to make transactions and don't want to pay $5 for it then wait for the weekend, the mempool is usually cleared up at that time.
