Ethereum developers ： Five major reasons, such as users' taste of fresh food, lead to EIP-1559 Upgraded Gas Rise in price
8 month 6 Daily news , Ecological construction coordinator of Ethereum Foundation Trenton Van Epps Tweet and explain , Or there are five reasons for EIP-1559 Upgraded Gas Rise in price , Specific for ：

3. Some miners will Gas Limit Set below 3000 ten thousand , So that each block only uses about 1350 ten thousand Gas, Increased congestion ;
4.The secondary market fluctuated and rose ;
5. The user is sending a large number of transaction attempts EIP-1559 function .
In addition, for Priority Fee （ Gratuity ） Why higher than 2Gwei,Trenton Van Epps I think there are two main reasons ：
1. Each wallet interface （API） Still rolling out , So most users haven't even sent a new transaction type , It makes it impossible to adjust Priority Fee;
2.Gas API It will take time to adjust the algorithm to recommend the appropriate Priority Fee, So now many people are still observing and adjusting .
