when will the bitcoin fee be reduced or moderated?
it will eventually happen. people will either stop using bitcoin so the fees will come down or the spam attack finally stops and fees come down.
in the long term we will have a real scaling solution too which will mean fees will come down. but it takes time to implement things like LN.
i mean that even if the bitcoin value rises or falls the fee is constant in bitcoin ,unlike in ethereum where the fee is fixed not in eth but a particular USD value.
when will this improvisation take place in bitcoin?
so far as i know ETH fee is exactly the same as bitcoin and it goes up with price and also goes up ridiculously faster than bitcoin when there is a clog in the network from ICO transactions or just some smart contract using ETH network to make transactions.
