" Why invest?

Stratis tokens will fuel the Stratis blockchain and also the private chains (side chains) that will be part of the Stratis network. Stratis tokens can be used as a payment method for the decentralised app hosting functionality built into Stratis and the fuel for the Blockchain-as-a-Service platform. We will be developing and engineering many platforms and services on the Stratis blockchain that will help to build a healthy eco system around the Stratis Blockchain.
Consequently, adoption of Stratis and its private chains will entail increased demand of the finite supply of StratisCoins. "
