Don't get me wrong we like decentralized storage space. However, we have decided to sell all of our Siacoin. Let me explain why. Sia is the project of Nebulous (Nebulous, Inc. is the parent company to Sia). Nebulous and other early backers of the project control another coin by the name of SiaFunds.
The fees that that are generated from contracts on the Sia network accrue to holders of SiaFunds and not Siacoin.
We simply prefer to hold coins where the value from the network or service accrues to the coin holders themselves, and not just insiders.
