So, Your idea(blogged it)-hive(process medium)-viewers(the recipient of the idea). Probably, the flow is like this? HIVE will keep your idea for you as its user and will let others know it since it will posted publicly(if you allowed to) to either share your knowledge or entertain others as they view your thing. And also, to operate, gas or something alike is necessary. So probably,this where the hive tokens being part of the system. Now, why the price of the token is getting cheaper? The war on hive isn't enough? Just joking. The users should be less or the token producers just so fast that the demand was already filled up. Well i bet there are so many reasons to these. I just pointed out what I understand.
