What do you think, is it possible to have zero transaction costs for bitcoin/altcoin. At the moment there are many fees and are they justified and impossible to get around or is it possible to reduce or even remove them in the future?
There was a time where this was possible for bitcoin but now you should forget about it, the model of bitcoin is to replace the block reward needed to maintain the miners with the fees of the users of bitcoin, so it is not possible the miners are not doing this for charity, they are mining because it is a lucrative business and if you want to use the bitcoin network then you need to pay.
