"Dai went live on the Ethereum Mainnet in December 2017. Since then, it has kept a stable peg against USD as the price of Ether fluctuated by more than 94%. Today, more than 1.5% of all Ether is locked up as collateral in support of Dai."

If you're interested in long term winners, taking time to educate yourself on Maker and Dai could really pay off nicely in 5 to 10 years.
