Yes, it's hard to understand isn't it. Look at Myriad, the original multi-algo coin. Its stats page and block explorer have always worked, wallets all work, links on the website all work. If you check the 'myriadteam' github you can see the development is very active, multiple community members volunteer their time to keep the coin up to date and add new features.
Now look at DigiByte. They're using the exact same 3 year old version of bitcoin core that Myriad used when it launched. A month ago they claimed to be working on 0.12.0, but a quick look at their github shows all they've done is forked it without making any commits.
I agree, I think this coin is manipulated. It's probably mostly the instamine that gets shuffled around on the orderbooks every day.
