You may not have heard of the Dai coin as it is a newly launched cryptocurrency. The feature of this coin is that it is a stable coin.
You can buy it on the Binance exchange. The price is around $ 1. The essential feature of this cryptocurrency is neither falling nor coming out of $ 1. So it is fixed at $ 1. I don't think this cryptocurrency will evolve as it has a fixed price.
This money can be stored in various wallets and platforms. There is also mining for DaiCoin.
You can also exchange any ERC20 tokens.
