As the interest is 0% on the deposit, I guess its also 0% on borrowing. So in theory if you were a whale you could collateralize a lot of crypto and borrow a huge bunch of DAI for free, then ship it over to another protocol that gives a positive yield and be earning “free interest”.
The rates quited on maker dao are fixed or dynamic? Today 0%, tomorrow could be 10%?
Defi and the course is very interesting, but also a bit overwhelming 
Thank You! I will check it out.
Thanks for that!
super interesting site
Hi Amadeo, I have a question of how DEFI calculated the Total Value Locked for Compound.
On compound website, it shows $1.7mil is being supplied (= locked)
On DEFI pulse, that value is only $780k.
Thanks.

Hi @amadeobrands
I’m having fun with my trial and error using the kovan test net,
I did supply eth worth $389 on compound and make it a collateral
and I borrow 10 Dai there and I did locked it in Oasis but the dai savings rate
is 0%. but its fine because this is just a test net, I’m just having fun exploring.
As of now my eth on compound is already $394 wow amazing
how I wish it is real not just a test net. lol 
Thanks Amadeo for this Defi 101 course very informative and I learned a lot.
Take Care always.
@amadeobrands what are your thoughts on the balancer liquidity pools? RIghts not using renBTC and wETH I am receiving around 77% or about 6% a week paid out every Tuesday. Balancer pays in BAL, and I am worried about the long term value of BAL, what do you think? Thanks, lots of great information in your class.
I know the BAL team and they will keep on building this is just the start 
Smart pools will still come that will be insane man.
To get a good understanding of Balancer I would recommend you check out:
The model of re-balance and adjustment determing on the FEE etc is super mind blowing.
Would love to do a more indepth recoding on it when the smart pools will come out that will change the whole financial landsacpe significantly.
I generated 1 ETH through the https://faucet.kovan.network/ address. I then minted 100 DAI by leaving 0.5 ETH in collateral on Oasis. I then supplied 100 DAI on Compound for the liquidity pool at 3.67% interest. Then I withdrew my 100 DAI and then repaid Oasis the 100 DAI I owed and took possession of my 0.5 ETH back. After all this I ended up with a balance of 0.6765 ETH in my wallet. It cost me 32.4% of my initial capital just in transaction fees. This is crazy, the transaction fees are way too high for anything you try to do in DeFi.
I don’t get this whole thing of minting DAI using ETH. This just seems like a waste of money (ETH). Transaction fees + interests + having to leave more in collateral than I want to borrow just makes it pointless to me. Why not just swap ETH for DAI if you need it? (0 collateral, 0 interests …)
So far, I like the whole concept of DeFi, but I haven’t seen any real financial product of value yet. Interests is super high to borrow and super low to save and transaction fees are just ridiculous (even worst than banks).
Hi All
I was creating a maker vault on oasis this morning and the transaction fee is 64.59$. I think that is excessively high. Is this normal?
changed some ETH to Dai with unicorn exchange and put it on compound to supply the transaction fee is just to high, for putting in 10Dai tosupply it would is 0.066 ETH what is about $29 so this is not lucrative at all for now
I think Maker is a good platform to invest and possibly make gains depending on your initial investment capital and your stomach for risk. I logged on to Oasis with my metamask wallet, I will put in my position later but the course really taught me a lot about Defi so far, I listen to Ivan live stream everyday but this course really has me interested in this space. Keep up the job guys!
I played around with kovan test net, got some dai and deposited to the 0% interest bearing savings account on oasis. When I try to pay back the dai and exit my 0% position it wont allow me, it looks like this:
I can only pay back the maximum amount, which I cant because I paid more interest on the loan than I got from the savings, or then I can pay back only the interest.
Is this normal? You can only pay back either everything or the interest? So if my collateral drops in value and Id rather pay back some DAI than deposit more collateral, this is not possible?
It is very lucrative it is just not really fit for small amounts DeFi is becomming a 10K ++ USD game 
Projects like xDAI or others will solve these issues.
This is a feature not a bug of the protocol
Since it is the test net … there is I think not that much outstanding etc so what happens is that you either need to close your loan or generate more. In the mainnet this will not really happened but if it does yes you do need to pay ETH to top up.
I’m thinking the same thing, but isn’t everything built on a bubble?
This morning the gas price for creating a vault is hundred and $128. That’s almost double what was yesterday. This is ridiculously high and not sustainable. The high gas price makes it unaffordable to use the protocol except for very large investments. What is the fact is that is making the gas prices so high. Visit network congestion, a higher ether value or inefficient code? What is your opinion?
Furthermore looking at at 150% collateralization ratio in return for a synthetic stable token that is peg to the dollar is in effect the same as shorting the ETH market under leveraged. If the value of ETH goes up the position will end up being in a loss. If ETH goes down in price you will get liquidated and penalised the liquidation fee. So except for the fact that you can use your DIA token in other also risky DEFI protocols I am struggling to see whether opportunities is at this point.
I’m a little confused. I went to set up a DSR on Oasis and see that the fees are very high, but confusingly the Savings Rate for DAI is 0%. I must be missing something? Even the corrupt banks give a better rate than that or am I looking at this wrong?
And it looks like a 3% return on Compound. So, I guess you must shop around for the best rates but just seems interesting that there would be such a gap between offerings, 0% - 3%.
Thanks
Gas price way to high to do experiments with DeFi right now because of the yield farming hype. I already experimented with maker dao and dai about a year ago or more…i was excited because i was thinking like this;-
that i would lock in some eth and get some dai…then go and buy some eth with that dai so that when the value of that eth went up all i would have to do would be to return the initial amount of dai i borrowed to get my eth back plus the eth i bought with the borrowed dai… worth while maybe if you had a ton of eth to begin with…
…so that was my take on it back then. Now it has changed a lot and probably far more effective just to stake eth or as i saw here in your videos supplying liquidity to something like the curve protocol may be worth while but none of these things are really worth it unless you start of with a lot of liquidity in the first place to provide, as far as i can see. Am i wrong? please correct me!
Going down already take your change and make some real profits gogogo
