Oh the userbase wil grow! ethereum and golem based super compuer users will need siacoin to do the storage for the super computing peopel will be doing!
seriously wwhen someone figures out that you can simulate the entire universe but you neeed the entire ethereum network to do it they will be addicted, ids will only wwanna play games usng an ethereum based system where you get the power of millions of video cards nstead of just one!
imagine what a million video cards could do for video game graphics! you could havve pixar movies inreal time
and for stuff like that you will need siacoin to use all the extra storage!
siacoin will have a program to install on old compuers tooo siacoin lite that lets you expand ur rig and run storage on evenolder comptters to take advantage of every gigabyte
