In the network Callisto implemented a treasury model. A certain part of the reward from each block is allocated to the Callisto team to finance the further development of the project.
As for the prospects, the cold-steak gives an excellent alternative to proof-of-stake competitors: there is no need to run "masternodes", it is enough just to transfer the coins to the corresponding address of the contract.
Especially strong demand should grow with market depression and an increase in the entrance threshold in the ICO - here the project will compete with Tether and other "stibblkones" as a means against devaluation of crypto-currency reserves.
In addition, the steak must create a deficit of the offer of coins at open tenders and thereby increase the price. but this will only work if new projects not related to stealing and management of the reserve fund appear on the platform.
