Bought it, sold it, Ethereum has its own storage module so I think the development stages of Storj, MaidSafe, Siacoin and others may not make it out of early development. As a speculation point of view, all coins will go up and down and this is not the first time Storj has gone up, or down. Trading is just a glorified Casino, be careful. Hold as much Bitcoin as possible for the future, it is what all Alt Coins trade against.
