Sia is also intending to market to large enterprise customers.
I don't know if I'm the only one, but I never find sia's opinion or project interesting and beneficial for the existing users or assets. It's like a good idea but cannot doable and applicable efficiently for the moment.
There is big need of decentralized file storage. Every tech giant offers its own cloud. Samsung, Google, Apple, ... and for every service you have to pay, after you reached the limit of data volume. I am not using this services, because I don't want my datas stored at someone, who I dont know, who I don't trust, who is selling all my profile datas for commercial interests without telling me.
Services like Sia are the future for everyone, who is interested in control of his own data. So buying SCs is not only trading for profit. It is support for their work, their idea and motivation to go on. And then we will have easy to use applications to store whatever we want. With full control. We will have to pay for that. Yes. But this is absolutely logical, because noone there who is selling the informations from our lifes for profit, power and influence. And maybe sometimes for our own disadvantage.
