No my friend,
I think bitcoin transaction fees id is not fair currently because of I want to process a transaction worth $100
I need to pay atleast $20 to process the transaction....
Currently it is not Okay...
May be not 20$) I think average BTC transaction fee is about 5-8 $. Of course there a lot of criprocurrencies like DGB with very small transaction fees and it is preferably to use it.
You have to remember the transaction fees of Bitcoin does not calculate through USD.
You are using Bitcoin, therefore, the Bitcoin miners and Bitcoin system use Bitcoin is the unit to calculate transaction fees.
Beside that, transaction fees depends on the total size of your transaction, more inputs and outputs, you need to spend more fees.
