The price will go up as folks utilize the SALT network to borrow money. Think about how much money is borrowed each year from credit cards and banks. If over time SALT can gain a share of that borrowing market (this share will rise along with the adoption of crypto currencies), the value of SALT tokens will rise on the back of the loans and inherent interest generated by them. The demand for SALT memberships will also rise as folks look to obtain them to borrow capital.
