ADA will have a stable coin like no cash, but it will first submit a smart contract to the ADA Network. This means that it will be able to be used as a method of exchange without interacting with a third-party exchange service. The network itself will hold the value of your ADA tokens according to their native value, which will be determined by incentivizing nodes to include it in their block rewards. You have to invest more in this project. I use dollarcostaveraging.io/for investing. It's a new great platform that all of my friends are using.
