Question to possible value of a siacoin

Example: Dropbox Plus: 9,99$ (roughly 10$) for 1 TB per Month Siacoin: (assumption) 1 Siacoin per 1 TB per Month

If this example fits then one siacoin couldn't ever be valued more than 10$. Or did I understand that wrong? Because for the people who are searching hosting it wouldn't make sense to buy sia cloud storage because it would cost more than an dropbox plus subscription.
