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?
it is unlikely there will be zero transactions cost
because to do the transaction you have to turn on your PC or smartphone
electricity usage also includes transaction cost
but so far I only know there are two coins that do not have transaction fee
Nano and IOTA
