Dealing with crypto’s volatility can be a problem. As much in the blockchain space know, DAI isn't the first steady coin in the space. Predecessors consist of Tether, TrueUSD and a few others. However the risk of all of these projects can be that the custodial party keeping the true US dollars will refuse redemption of the steady coin for just about any regulatory reasons. This will go against the ethos of crypto becoming permissionless.
