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?
I believe that you cannot remove transactions costs for bitcoin because miners also need something in return for confirming a transaction. You may reduce it by using the mining device's hash power efficiently. In the near future, the value of a transaction cost will become insignificant to the part of service users because of the evolution of technology to hardware devices.
