A fee at this moment is a very low value in USD (0,0001 BTC / 2cents).
But - lets hope and pray - when bitcoin skyrocket to prices like 1 btc = 100000$, the fees will be huge in fiat value!! People, for a transaction of 10USD (0,0001BTC) would pay 10USD in fees too!!!
Or am i missing something here?
fees has already been changed a couple of times until now. it was not always 0.0001
BTC for fees , i don't know exactly what was the amounts before but i know for a fact that it has been changed more than once in history of bitcoin.
so in the future it is not a problem to change it again for example if the price skyrockets it can be reduced or if the block reward decreases a couple more times and price goes down it can be increased.
