Been out of the loop for quite a while. Can we now 'mine' Storjcoin by offering storage to the network? If so, is it profitable? At what rate etc. Interested in offering up a few TB.
It's called farming, rates are difficult to establish as they depend on several factors, the more data you store on your node the better.
However to get that data you need to be online 24/7, have good, reliable internet and more people and companies uploading files to the network.
It is pretty competitive as there are tons of farmers, I've been farming on a spare machine since test group A, over time got quite a few SJCX.
It is not advisable to spend a lot of money on hardware (namely HDs) for Storj right now however as storage demand increases, opportunities follow.
As things progress determining rates for sharing storage may become easier.
In the meantime you can keep an eye on current monthly payouts to have a very rough idea.
