The end result of Filecoin will be extreme centralization just like Bitcoin mining unless there are extreme legal issues that makes everyone scared of being part of the network (e.g. child porn.) Thus there will be a few ultra large cost optimized providers probably similar to BackBlaze that handle 90% of all storage on the network. Does that extreme centralization fulfill the vision of Filecoin?
