It's true, the ETH Gas Fee is often unstable. Sometimes when the transaction is solid, the ETH Gas Fee is quite high. As a bounty hunter, we have to look at the moment when gas is cheap to transact because it will save costs (maybe only $5 for one transaction). As a Lover of the Ethereum platform I hope Vitalik can stabilize Transaction Fees like the BSC or Tron Platforms. Small players in the Crypto world expect this to happen this year.
