DAI is a stable coin. I have explained what that means on my blog. Check it out if you're interested.

But DAI isn't just any stable coin. It's pegged to the USD and is built around the ERC20 protocol.

So why should you own it?

Simple. Because it's basically the crypto equivalent of the USD.

Except it's a hedge for market failures.

See, trading DAI against BTC or the other way around yields you 2 cryptocurrencies. But one is stable and tied to the USD, while the other isn't.

So technically you have USD and BTC whilst trading those pairs.

So you should own DAI because it's a hedge against market failures.

The USD can't move 6% in a day, up or down.

Bitcoin recently did this.

So by owning something that stable in your crypto wallet, you could potentially offset large losses, of course with a few stop losses in place.

That's why you should own DAI.
