I'll be honest that wasn't that clear to me as well, I didn't understand why it's without fees but there is a max fee anyway thanks for clearing this up, now I understand it pretty well. I just have a question though did they change the mechanism? Was there a fee before? Because as far as I remember there wasn't any fee, you're allowed to send as many xrb as you want in a single hour without paying for anything, maybe I'm wrong though, can someone clear this up? Anyway isn't xrb promoting feeless transaction? But why does there own raiwalletbot charge fee for more than one transactions in the same hour?
I made a poll several months ago. Users prefer to have small fees instead of time limits. There were fees in telegram bot. Always. Otherwise some attacker can spam bot with thousands send requests for free & literally disable service for all other users & spam network with bot server. Every transaction require server PoW calculation. In desktop wallet or web wallet user can make PoW. In telegram it's all up so central server.
show me the Roadmap please
