This is very good work. Clearly explained. Well done with the research on DAI. You have indeed put this together from a point of understanding that you have attained from your close study on DAI.

DAI can also be traded on that Oasis or you can use a centralized exchange like Coinbase. You can also check other exchanges by going to coinmarketcap or coingecko:

I better lookout for Some DAI stable coins on those highlighted exchanges and yes DAI is a public coin that is live on the Coin marketcap ranked #36.
