I personally think you should cut STORJ. I have been on and off involved in the project by sharing my space. Overall, I think it is a great concept, but as you already stated, it struggles in the tough market. As a storage "miner", the ROI is horrible and is only worth it if you have a ton of extra space, leave your computer on 24/7 and have a fast internet connection. I hope the project succeeds, and will keep contributing, but I wouldn't look to keep it in my portfolio.
