So it's DAI, a decentralized stablecoin backed by ETH.
History has proved that Dai succeeds even in a falling ETH environment. When the value of ETH fell from $1,400 USD in January 2018 to $400 in April 2018, the Dai systems incentive structure successfully kept the value of Dai pegged to $1 USD.
Unlike Tether (USDT), Dai is completely decentralized. You can see how it works at https://www.hb-wallet.com/post/how-dai-stablecoin-works
What do you think about this stablecoin and its future? I cant say anything for this coin, since I dont use it, but after reading the reviews of people I think Ill take a closer look
