CeFi, DeFi: The renewal of Savings

These days banks have the monopole of savings rate but a new trend is coming up to bring new adversity. It offers new rates and new rules providing an alternative to the old financial system. In this article you will see what can the alternatives on Fiat bank saving accounts(Fiat is currency such as Dollar, Euro, Yuan…) within the crypto ecosystem.

Disclaimer: This is not a financial advisement. Investing is at your own risk. This article only goal is to provide information and explanation on this new system growing up.



stablecoin is a reproduction of a currency such as dollar. It can be provided by a companyTether with USDT, Circle with USDC) or by a smart contract (DAI). Those entities or programs ensure that they have one dollar in the blockchain equals one dollar in the banking system.



Centralized Finance  (CeFi)

Centralized Finance is very similar with our current banking system. You have an entity/company in which you invest your funds. These companies provides large amount of financial product which is a mix between traditional banks and new economy.


Decentralized Finance (DeFi)

Decentralized Finance retakes the idea of no middle man as wanted Satoshi Nakamoto the Bitcoin founder. The process is fair and transparent while allowing everyone to use it. It’s permissionless and automatized by smart contract running on Blockchain applications.


Banking system

In current banking system we can earn money by putting our money into financial product. In France we have the “Livret A” a flexible earning placement which provides 0,5% per year

It doesn’t even repay inflation.


Current CeFi such as Coinbase,Nexo,Crypto.com are providing a lot of financial product within which stablecoin (crypto that is pegged to the dollar).

You can earn up to 12% per year


DeFi product such as SushiSwap,Aave, Oasis (cf my article on Oasis here) are providing earning with lending, farming, liquidity provider program. 

It can goes from 2% to 30% per year depending on the platform and period.


Centralized finance platform such as Binance or Crypto.com, on which I did an article a year ago, provides good rates while having the insurance of a company if there is any trouble (fund loss, helpdesk…). They provide currency exchange platform (including Fiat), borrowing & lending, earnings, derivatives, and many more.

They make money mainly on exchange transaction fees. For them the goal is to attract user to have a maximum of volume to improve their revenue.

They provide a lot of earning possibilities and aspire to become the Bank 3.0.










Aave is a remarkable Lending & Borrowing platform. You can borrow by putting a collateral asset such as ETH and borrow a stablecoin.

The lenders who provide liquidity are rewarded by an annual yield percentage:

Rates can change according to the market needs and you can withdraw your fund at any time.

This solution allows lending and borrowing without middle man. The trust is now on the smart contract.


SwissBorg is a company that provides Yield (revenue) when providing asset for them. They have an algorithm that select the best platform yield percentage and gives you daily reward with a security in case of loss (special program, insurance…) .

This is a good use case of Company using DeFi.

Liquidity Providers


Uniswap is the most used decentralized exchange platform. To be sure that their is liquidity on their exchange assets, they reward people who provide liquidity. They will be rewarded by getting tax fees of the transactions on this pair.

Let’s say you have ETH and DAI you can provide liquidity by putting ETH & DAI into the Liquidity Pool.

You’ll get a percentage of the fees as a reward (according to the amount you provide divided by total pool amount) as you can see above.

Yield Comparison




6% On flexible Terms

8% if Premium

12% If Premium and 3 Month Fixed terms Period


5% on Flexible Earning

Instant withdraw

Up to 8% on fixed terms savings


Average of 20% with Premium

Standard 10%

1 Day to withdraw



At time of writing:

Around 8%


At time of writing:

 Around 8%


At time of writing:

Around 8%

In this example I used Yield percentage on USDC the most secure stablecoin on the market at the writing time of this article. It is backed by Circle Square company with many audits on their accountability to verify that every USDC on the crypto market is backed by US dollar.










To conclude, there is a lot of ways to invest your sleeping money elsewhere than in your Bank account with low interest.

 Of course this new bank and new world may not be as secure as this big company bank yet they have the merit to offer an alternative.

Afterward, if you want to stay in more centralized way as in your bank you can use centralized platform that offers security. 

If you want by conviction to fully avoid bank system DeFi offer a great opportunity to be sure that you have financial liberty and freedom. Be careful if a bank can be robbed so is those platforms. Even if the risk stay very low, their isn’t 100% security in neither in those solutions only pros and cons. Then it’s up to you to make your own decision according to figure on the right.

On my side I’m lucky enough to have Swissborg Premium so this is where I rather put my money. Yet I’ve used DeFi & CeFi and I was very please by the services, I just went where the yields are higher (and provides enough security).


Hope this article can help you to rethink on how to use your money and gives enough information to improve your knowledge on that part.

Don’t hesitate if you have any questions regarding this topic!

Last options are crypto credit that I’m not recommanding as the interest rate is high. Eventually you have a FIAT wallet to stake your currency as you do with your bank.




MCO is the utility token of this application. It allows you to get the VISA Card (even if their is a free MCO card). Visa is a Crypto.com partner and that’s why it’s, for me, the most interesting banking project right now.

Their is various card options. The first one is free and then you have to stake MCO to get a better card. The advantages of getting a better card, they can be reward or purchase rebates on Spotify,Netflix and so on. You can see all information here

MCO can be useful to get more earning percentage on Crypto Earn with 500 MCO staking (approx. 2000 dollar). You can have discount on credit invest. Normally when you use crypto invest it takes 18% of the profit made. Instead with MCO staking it’s at 9%.

CRO is drop yearly by holding MCO. You can find MCO price charts here.
