This is a utility token, used in system. For Sia devs there is no sense to grow because it will be expensive to use their system. To start work with system you need 2000 sia. If it will be a dollar, who will start work with system. Now there was asics created and it can be pumped, or it was already pumped:)
Thanks for your opinion i read why it was not grown successfully, in despite of that siacoin technology can be used and it may lower the costs if that will change in the future we can saw a $1 price.
