But what happens with 2000 siacoin for making a host? Will they come back to me?
Yes. All the coins from those 2000 not allocated in contracts return to you instantly. The rest used as collateral return too as soon as contracts expire
Thanks very much, that was a very helpful response. I was wondering if instead of renting on a per file basis you could simply rent an amount of storage (1GB, 1TB, whatever) and use that freely. I imagine that's what will be solved by the Dropbox type development you mentioned.
Much appreciated,
Cheers
Actually, it already works that way: you make an allowance for a certain amount of storage and certain duration, let's say 200Gb for a total of 5 months, so you pay 600SC upfront. You start uploading files: first file is 2SC, second file 15SC... after a time you download the file#2: that is 0.1SC in bandwidth... You upload a new version of file#1: that 3SC...
By the end of the contract you receive back the rest of those 600SC in allowance you did not spend. The only difference here is that uploading and downloading is not automatic like Dropbox (not until a tool like SiaDrive comes): you have to select them in the Sia UI every time you need to upload or download those files
