I see that a new section on Bitcoin-diamond has appeared at all and my comment will be the first not only in this topic, but also in the section on Bitcoin-diamond.
Although this coin was created as a result of a rigid fork exactly a year ago - in November 2017, little is known about bitcoin and diamond, little is written and spoken about it, and BTC fans usually criticize all new bitcoin branches. And having read the text of the link indicated here, I didn’t learn a lot for myself. I haven’t even found what bitcoin diamond bandwidth is (scalability).
I believe that we need bitcoin branches, in any case they should force BTC to improve and create healthy competition.
