I just have fopund out, that sia is a project I will have a look at. Well, compared to sjcx it is yet far behind, but I am pretty sure when the block reward will halfed, the price will sky rocket. No doubt on that.
Did you mean that Storjx is behind Sia? That is right. Sia works in the live production environment now and you can upload and download files. You can make little money by renting out your space. Sia is the only live product in this space.
