Lots of times stuff like the use-case are for new product offerings. Like if a company like Vivint wanted to offer monthly-rotating-cloud-storage of security video files to their customers… they need time to sell it to more and more of those customers even if they could handle huge loads on launch day.
Kinda like Storj: having to prove your solution has been engineered to scale… but it still takes time to bring on customers to consume the capacity.
