Thanks Hakkane for all your replies
I also have a question ! Uploaded files are encrypted and split, is this process done by the client ?
My pleasure to help
Yes, files are encrypted by the client using the Twofish algorithm (one of the most secure that exist) and the splitting and spreading of the file among 30 hosts is also carried out by the client using the Reed-Solomon algorithm.
Sia really has failed. The first mistake was that you need to have atleast 2000 sia to sell your storage. That would have scared some people away. And people list it in one of the best coins to invest in.
Those minimal 2000SC are called Collateral, and it a guarantee you offer that you will keep your promise of hosting the files during the whole contract. If you are a good host, you receive them back. If there was no collateral (and this is the concerning case of Filecoin or StorJ), hosts would drop the files they are hosting as soon as another HDD-mineable coin was more profitable than Sia, thus making the files unavailable. Do we want a shit-coin in that conditions? No, for that reason collateral exists. To be a host is not an experiment of a weekend, it is a compromise as you are hosting the files of other people, and that entry point of 2000SC is actually very low. Don't you really have $16 to offer (that will be returned if you are a good host)? Seriously??

Sorry to be a D**khead or so but reality is that it was something new that had to prove it self. You probably chased the hype around this coin until reality hit and people realized that the devs can't deliver. If you are unexperienced trader learn this not to jump on board the first 6 to 12 months. Let the market decide what they think. it is not you nor me who will decide the price of Sia but the market. And now, if you look at the chart, every uptick is being met with more sellers. This means that the market doesn't give shit anymore about the devs of SIA. if they did you would have seen prices going up and not down. So basicly, the devs of SIA are working for nothing right now and have no future. Probably can go back to work and become wagecucks again. Not that I care since they don't care about the price neither. So let them proof us wrong but the odds are pretty much against them. Better buy some litecoin or ethereum classic or waves or whatever. Buy what the market supports. Not some faithless coins.
And what are devs not delivering, according to you? Sia is a working storage network currently offering 3.5 petabytes of storage among more than 700 hosts worldwide distributed. You have hosts at less than 50milliseconds of ping of every bigger city in the planet (which other storage provider can claim that?). File contracts are being formed every day and renters are uploading and downloading files. Take a look at the growth of file contracts:

So what are they not delivering, according to you? What you might mean is that devs are not making you rich fast? Sorry buddy, but your investment decisions and their consequences are entirely your fault (or your success). Devs are not here to make you rich by you speculating with the price of a coin, devs are here to keep making a better product. And after what I have exposed it should be clear they are doing an incredible work in that sense.
