So regarding the difficulty algorithm, ive just seen a video about a person's mining experience with the Ubiq coin:
https://youtu.be/_7DDbdZ7EboThis guy tracked the ubiq network difficulty and hashrates over a couple of weeks, and from his charts it becomes clear that Ubiq can deal much more rapidly with high fluctuating network hashrates. Ubiq has implemented a new difficulty algorithm called Flux earlier this year, and apparently it is working. Ubiq had to improve their algorithm for the same reason; unstable block times with rapidly varying network hashrates.
Now i think ive seen the Flux algorithm mentioned somewhere in regards to dubaicoin, but im not sure if it was developer related or something. So if dubaicoin developers arent looking into the Flux algorithm yet, maybe they should? It could be a good starting point to fix this problem once and for all?
