Ask HN: What is your opinion on DAI a stable cryptocurrency built on Ethereum?

In my opinion, it's delusional (at least for now) to believe that a massive amount of businesses will start accepting crypto like Bitcoin without selling it at the market value automatically. Businesses need stability and we can't ask them to trust a currency that can lose 80% of its value in a few months. Businesses want stability but they also want to maximize their revenue by eliminating unnecessary costs. The current credit card processing fees are around 2-3% which is huge! By accepting a stablecoins like DAI instead of credit card payment a businesses could save a lot of money. I would be curious to hear what HN thinks about this.
