First, is the short-term crypto market crash as the price falls causing investors to make a lot of transactions on decentralized trading platforms causing GAS to increase in price. and If high gas fees still shock you then you are probably a crypto newbie this always happens when prices go up, if you see the market is all green then you may also encounter high fees , the number of users can also affect gas fees, the higher the user, the higher the transaction. I have been trading in crypto platform for many years so I feel this is very normal.
