From what i understand the fee is not fixed and can change without a hard fork.
Now i get your point but i believe that datacoin is not only a place to anonymously store data but also distribute it super fast to many many people. Most times even if you store something somewhere those who dont want it can by force make it not accessible but when something will be on datacoin blockchain will automatically be on thousand computers without actually needing to find it and download it.
So thats how i get it. Its more about spreading the data faster...
Again look at perfect dark and share, it works like this.
There is Bob and he is running
Share<--official website
Share constantly has me downloading and uploading pieces of encrypted files to people who I connect with and pass files onto and they do the same.
If I want to download a file I can go to one of several sites where people post the keys for files or use the in client search to query by keyword, tag or filename. I query my peers and they respond with the data they know by querying their peers and so on. Once someone finds a person with the file or people with parts of the file, the files are discretely routed towards me via direct connections and through my peers. And as data is dispersed through the network almost all files can be found eventually. In fact you are required to download a certain amount of data before you can even start choosing what you want to download. The more random data you host the higher priority you are, the same goes with uploading.
Lets say Bob wants to save a file on the Share network.
Bob wants to upload a file, so he opens Share and tells it to upload it.
The program goes and encrypts the file and splits it into chunks and then starts giving it out to whatever peers I am connected to in order to start spreading it. Now if anyone queries with a file regarding the one Bob put up peers will end up either having pieces of the files or using bob as a node to spread it to whoever is asking for it.
This is the OLD way of doing decentralized anonymous sharing. The Next Gen was Perfect Dark
There is Lisa and she is running
Perfect Dark<- official site, use google trans as the dev was japanese
Perfect Dark starts by making Lisa pick a username, encrypting her IP and then add a lot of
nodes then she can pick how much unity storage IE how much space she wants to dedicate to hosting random files.
The more storage the higher priority just like with Share. Perfect Dark does a better job because while it is running it downloads and uploads even more data and you can even set it to delete unity data after a period of time for it to be filled with different data. You are required to essentially maintain a connection with the perfect dark network and act as a node sending and receiving and rerouting data and you are compensated with the ability to search and query other users again for filenames, tags, or by upload ID. Uploading is the same as with Share, however in Perfect Dark if you can see a file then you can download it as it means that someone has part of it where as in Share it just means that someone knows of it, and more often than not in Perfect Dark you can get a complete download as you are broadcasting your need for parts that gets pasted onto other people so you can be helped much faster and get your file downloaded in a much more timely fashion. Share can take months on rare files, Perfect Dark only takes a few days on rare files if you can get the query. There is even a continually updating message scroll that anyone can put anything on as long as it is text and everyone running perfect dark will see it eventually. Perfect Dark furthermore has the ability to host entire websites and forums and such though I have never taken advantage of this. Perfect Dark is superior mainly due to its much better networking and p2p functionality compared to Share.
All in all these are both vastly superior to datacoin, are free, will never require 500GB of storage unless you want to have that much and are smarter and easier to use as a whole and don't run a stupid scheme with fees in order to compensate for a lack of understanding. So please, fix Datacoin. Stop being an altcoin and be something interesting.
