( I test today)
it is never slow if you pay higher fee than other people. it is like a competition. i pay 100 satoshi per byte and you pay 110 for example and obviously miners will pick you over me. and if a third guy comes and pays 120 he will be chosen and so on. now imagine there are 10,000 transactions with higher fees than yours that you have to compete with
This undermines the whole idea of Bitcoin as money
Ultimately, the competition of fees is meaningless since money should facilitate the trade and not hinder it. Ideally, it should be in the opposite direction, i.e. miners competing between themselves for the inclusion of transactions in the blocks, and that should cause the fees to decline and not rise over time. It is basically the same as the matters stand with banks. Some of them are offering payments free of charge altogether if they want to attract more clients, and that's how things should work in general
Miners don't have to compete amongst themselves in terms of fees. They just have to compete with respect to finding the new blocks.
That is a slight difference between banks and miners because if one miner keeps finding blocks, the transactions will have to go through him.
