Ethereum has been known for a long time about high gas fees, and it has been popular with traders,
therefore traders are also reluctant to use Ethereum as a transactional tool,
just imagine sending $ 10 in fees which must be paid $ 1- $ 2 if the network is full.
Now the transaction fee can be more than $3, even though ETH Gas is below 100 but ethereum transaction fees are still expensive, this is because ethereum prices have risen quite high so that gas costs have also become very expensive even though they are lower than last November.
as i know , if sharding already implemented in their new developtment it could decrease transaction fees ( if i didnt wrong with it ) for ethereum community its really be main problem now , and if compared to another blockchain they affraid there are many community shifted .
