It takes time tho and in its own industry there are other competitor like

Maidsafe, Storj, Burst [HDD Mining + HDD Renting Service + Storage Service]

Somehow some of them is not a direct competitor to each other but still, it falls under the same categories.

In my opinion

Maid > Burst > Sia > Storj

Storj has 500M supply in total
Maid has 452M Supply and increased time by time
Burst has 1.7B and increasing and capped at 2.1B
Sia has 21Billion which makes it price hard to get to even 1K satoshi

Right now sia is having only $15M marketcap which is still consider low and is a good entry point for people who wanted to get some dirt cheap Siacoin. To achieve $100M marketcap, siacoin will just need to hit around 350 Satoshi+- and they can did it. The total supply is just too huge, if they manage to cut down the maximum supply, we will have a different case there
