I think the reason for the decay gas eth on the grounds that the volume of exchanges against eth has diminished radically so the current Ethereum network isn't so occupied as in the past. Meaning the Ethereum network right now not an excess of occupied that is the reason diggers can undoubtedly handle every forthcoming exchange.
the simplest explanation? the ETH network nowadays are not congested and why? maybe because users are using ETH network now lessen compared on what we have in the last year specially in 1st and 2nd quarter of 2021 when Ethereum fee is almost the same of Bitcoin transaction fee.
and also this is something good for ethereum users, though i stopped using Ethereum since last year instead i only has ETH for long term .
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.
I did experienced paying 18 dollars fee sending only small amount but i have no choice because i need ETH.
