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?
Not really , because fees is a part of the developmental asset of the transaction where it exist for a reason. But if you want to find a low cost transaction you will need to find a local wallet where there is a minimum amount or cost of transaction depending on the rate of time of transaction to be successful you will just need to find it and also support it.
