Often the simplest answer is the right one. What is going on with Qora and all these dumps and sells?! Blatant price manipulation?
After seeing this trend for so long, I doubt it. My hunch is that someone smart bought into Qora as a stake holder, possibly using multiple BTC source addresses. This individual (or individuals) have simply been cashing out.
Most of us feel that Qora is way under priced but I think some whale is happy with his/her 10x+ profits. However, instead of dumping the order book, they are making small stake sales each day (5-7m) and when the pressure increases, or is expected to increase, they pad the sell book. This is the smartest way to take profits.
There has been to much downward pressure, IMHO, for any intelligent person to hold down the book. I don't see how they could quickly cover their costs. Also, this type of behavior is often short-term manipulation and small dumps have been going on for a long time.
I really think what we are seeing is distribution at work. This feels bad if you want to see Qora rise in the short to mid term, but this is good news for distribution. This whales source will run dry eventually. It will happen sooner, rather than later, if/when people start paying attention to Qora.
And on that note, having CfB post comments on our threads is good news. I doubt he'll ever support Qora but I think he's an honest guy who primarily cares about the tech over any form of coin-fanboyism. His presence means people are starting to turn heads. If this really is a worthwhile coin, we want that. Including the skeptics.
