Today cost ether transaction is increase because some issues in net. Nobody sure don't know why it happened.
What you think - how mush we need to pay per ether transaction in future? if we speak about price that suiteble for all. Must it be low or medium?
I guess if there will be more update to fix the scalability problem of ethereum and it can reduce the transaction fees into almost zero. But this time it looks like there is someone that still created more and more spam transaction that makes the standard fee cost of ethereum blockchain is becoming so high.
