The main reason why the gas fee in ethereum blockchain is so high is because of many people are using the blockchain and transacting on it that makes traffic in the network.
This is a nonsense which was disprove many times, most of the transactions are almost empty, many of them filled only to 4%. Please just read first page of this discusion thread.
Actually I am hating ETH. The fees killing everything. There is no usecase for normal ppl, because of this fees. It is not feasable to even purchase NFT for 50USD or like that when you will pay 100USD in fees. WTF? 100USD is few months salary in some countries!
Or you can send parcel to the other side of the planet via UPS.
ETH will be done if Vitalik will continue sleeping. Rise of the SOL / ADA will kill it ETH in near future...
