Agree, if ethereum transaction costs can be reduced it will be a greater attraction for investors to use ethereum. Right now, the fee of transaction is very high even we using economy (Gas setting).
It depends on how you set gas price and gas limit for your transactions. It also depends on the default figures are given by the wallet you are using. Most of people don't know steps to customize price and limit and they automatically accept default figures that obviously always expensive.
If you set gas price and gas limit at low, please read the guide
How to cancel or replace an ETH transaction (Metamask, MEW, MyCrypto)I have worked towards making customized transactions many many times and I can tell you that it is still quite high no matter how you do it yourself. Go check how much it costs and you will see that it costs way more than it should. Ethereums increase is capped because of this gas fee situation and I think it will always be capped for a very very long time. Sure it goes up and it can continue to go up but those prices are horrible for each fee.
I never NEVER pay the preset versions, I am not in a rush so I can wait, which means I will end up spending the bare minimum price require to send without being cancelled and that is why I do not care about whats written on the preset ones and even the bare minimum that goes without being cancelled is above 35 dollars right now and that is just way too much.
