After having gone thru DeFi 101 twice now, I think I finally have somewhat a grip on the functionality of the different apps (synthetics was a mother#!"##% 
). Since the recording of this section of the course, so much has happened and changed, so some of this stuff was almost irrevelant as the users have decreased immensly, i.e. Chai and curve dont seem as much used as they were, unless I was looking in the wrong place So many new coins and platforms have been introduced that it is quite overwhelming!
I find that for me that being in the entertainment and creation industry I am looking to delve more into the streaming platforms (music, content creation, podcatsing, etc.) I know however at some point that I will have a use case for Maker/ Compound/ Oasis/ Nexus etc. Amazing tools!!!
To know that there is a way to get loans and accumulate savings without having to go thru traditional centralized banking is a mind blowing game changer. Additionally to know that one has the potential to be on the giving end of providing capital for loans via “pools” is wonderful. It´s a direct way of being abe to give back to help others and help the DeFi system to grow. I just hope adoption continues to grow and that people are not in this just to get a fast buck. Yes there is a potetntial fast buck to be made but I see this as having a mass potential to provide masses a certain level of freedom financially. The ball is so to speak put in the individuals court without some central figure breathing down your neck and manipulating the scene.
Maybe I did not answer the question but I am just awed by the potential of what is before us all… 
A really good project is AMPL. The protocol automatically adjusts supply in response to demand. This will fixed the issue we have with sablecoins, that are tied to the $. When price is high, wallet balances increase. When price is low, wallet balances decrease. Supply adjustments are applied universally and proportionally across every wallet’s balance. This means your percent ownership of the network remains fixed. https://www.ampleforth.org/basics/
As I see it you can either use it for speculation, as taking a loan and betting on another crypto going up in value. Longing a coin.
The other thing would be to exchange it for Fiat, buy something, and pay back over time when you get your pay-check, like any other loan. I would compare it as having your house as collateral to take a loan to buy a car. Now this is risky when the crypto market is volatile, but I do not know enough to say how big the risk is and when you would get liquidated.

I used the Kovan Ethereum network. I opened a Github and an Oasis account, and requested KETH. I was able to verify the transaction in kovan.etherscan.io. Not understanding everything, I tried to convert to DAI to earn interest. I was at oasis.app/save and that only works with real ETH, not tester KETH. So I got the error, “Browser ethereum provider and URL network param do not match!” I googled that error phrase and found that I had to use the address (https://oasis.app/save?network=kovan) that Amadeo Brands instructed in the HW. I rewatched sections of the MAKER DAO lesson.
Then I explored the borrow and save options on Kovan. I connected to my Metamask wallet, setup a vault and confirmed with 10 transactions. I locked up 1 ETH generating 738 DAI. ETH’s current price is $2215.53. My transaction has a collateralization ratio of 300.21%, $1107 USD/ETH liquidation price, 4% stability fee and .127847 gas fee. I verified the transaction at kovan.etherscan.io.
When I tried to lock DAI in DSR and earn interest, the DAI savings rate of 0% APY would make such a transaction a loss because of the fees. Coming soon to Kovan will be Lending in Compound at 3.11% APY and on Aave at 8.25% APY.
I would like to see a crypto debit card for US users and a crypto credit card that earns rewards in crypto for US users. There are crypto debit cards for non-US users.
I personally have used it on a loan to avoid a taxable event. This is a great opportunity to maintain the market exposure but to have sufficient funds to invest in real world applications, or maybe any necessity que may arise.
Maker is really cool, I think Maker will thrive more with large institutions and governments rather than retail. Roughly a year later from this course, we are seeing smaller dapps building for retail investors. I see maker as a place where treasuries of countries will be stored to earn yield and set rates for the citizens.
By borrowing DAI using your collateral, you have an opportunity to buy and familiarize yourself with other different coins on the market by testing your luck on expecting them to appreciate over time and pay off your loan. In other words, extra DAI one can obtain can also stimulate the cryptocurrency market further if the right coins are bought.
This is was a great exposure and practice to MakerDao:
Used ETH as collateral to borrow DAI on Oasis Borrow and Saving DAI to earn DAI on Oasis Save.
Practiced and learned the important MakerDAO protocol terms like Stability Fee, Dai Savings Rate, Collateralization Ratio, and the Liquidation Penalty.
Yikes! Gas fees are so expensive.
Thanks for the answer! 
Thanks for all the information, great content and lessons. Nowadays (April 2021) ETH almost 2,900$, the Gas fees very high! I keep practicing and learning more.
Thanks for the course Amadeo!
I think,I have to push the experimentation phase into the bear market, cause gas fees make playing around extremely expensive. But i had a few thoughts none the less. If the big selling point for defi is to bring access to money to everybody, i see a problem in the fact that you have to have money in order to get some more. A business opportunity would be to create a way to build a credit score in the defi ecosystem, other than by providing collateral. Now lets jump into defi 201:-)
really interesting and possibilities are endless. compound interest is absolutely amazing.
Hey @KK_Cheah
You can rather try this link https://oasis.app/borrow?network=kovan.
After plugging in your wallet, you can do tasks like saving and borrowing.
trying to do this may of 2021… gas fees are crazy. cant afford to do this assignment haha. maybe I missed something. Seem like this assignment is very dated. you guys should probably update your stuff soon, normal people cant afford to mess around with Ethereum anymore.
Hello @amadeobrands, I personally like the saving option in compound and earning cdai…It is a bit off to get your head around it but I have done some borrowing to get it.
Now more than ever I think a tool like this can help our current world situation but only time will tell.
HI Amadeo&fellow students,
Thank you for saving me some time and for the positive energy you bring to my desktop
So in theory:
• I invest in ETH and earn big gains
• then I would like to take out a % of my profits and I do so by opening a Maker vault, I deposit collateral and I generate Dai, because I want to save my profits in a more stable asset
• then the bear market comes and the crypto markets are losing momentum (prices going down for months), because I have a stable coin I don’t lose as much as I would holding crypto
• I have Dai and I want Dai to give me some yield so I lock it into a liquidity pool on Compound and I receive cDai for doing so. cDai is an additional stable coin reward for supplying the pool with liquidity.
• The bear market is over after a year and I unlock my Dai from Compound and by ETH with it again. I can also spend cDai and buy another crypto…
Is this what these legos are about? Did I forget something(like an additional revenue stream)
I appreciate all comments and answers :smile : ) (please write freely about my mistakes )
Hi @amadeobrands and all the forum,
Thanks for sharing all this knowledge! The fees are a bit high at the moment eheh! But I really like Compound, and I’m testing some of the functionalities.
It was a really insightful course about DeFi. Never realized there are so many option in this ecosystem. Wanted to try and test it out myself, but fees stopped me, they are too high.
The concepts are all great but as the market matures, it would be nice to see some solutions that could simplify the process for the masses. I can assure you that everyday people would most likely go cross eyed trying to figure it all out.
