The project isn't dead, in fact the product isn't even really finished. There are many possibilities of improvement, and that's why it could grow. Moreover, the public doesn't know well Siacoin, it's still an unknown cryptocurrency (except for the people that are in the crypto field). Therefore many businesses but also private consumers could be interested. After all, Bitcoin hasn't changed fundamentally since 2009, it's our world that has changed a lot.

I purchased cloud storage with SC, but... honestly, hopefully the price was really cheap (regarding other cloud storage services) because it was really complex, non intuitive and... well, let's be honest, I finally never used that space storage because when I finally was able to upload files, it turned my computer crazy when I tried to upload... I always had to restart my computer after a short time (info : but I'm able to play recent video games). My main goal was to test the functioning of Siacoin.

I'm supporting Siacoin since June 2016, and I really think it's one of the best project in the crypto field, but from a critical standpoint, it's not working properly for the moment. People don't want to spend time to understand how Siacoin works, to solve issues that they would encounter, without being sure that it'll work at the end and that even if it's 5x cheaper than Amazon S3 services.

Imo, I would say that it's important to still be aware that a lot of work is still needed for Siacoin to make a breakthrough. I invite you to try their cloud storage service for making your own judgment. It was still a great pleasure to finally see a project that is working, even if it was a little bit tough, and to experience it ! I hope it'll be easier and massively adopted in the future

DB Points, DBC, DBT, imo it's becoming more and more confusing. Add to that the fact that it's using NEO but for buying DBT it's using ETH and we got a token soap 

Moreover, I don't really get everything. There will be like a new ICO for the DBT, OK. The DBT will serve as a token for the exchange plat-form. But it's just temporary, isn't it ?

As far as I understood, you're planning to :
- Launch DBT sales
- Test the exchange plat-form
- Buy back the DBT

And then, "When DeepBrain Chain's public chain goes live, the token will b emoved onto DeepBrain Chain" (DBT whitepaper) ? So, basically, you will use DBT as a token test before launching the "real" version that will use DBC ?

I checked both whitepapers (DBC and DBT), but still I find it not clear. So if someone can enlighten me on that, thanks in advance.

I don't think it will really take off. Since January, the price has been divided by 50 which is really huge !!!   
And as it has been said, there's competition. In December, Voise had a good rally, it overtook Musiccoin in marketcap for example, and the change of logo maybe helped. But since then, not so much update... The change in the staff doesn't help at all neither  It looks like the boat it's not longer drifting, it's on the rock.
