On the other hand, this system offers individuals the opportunity to make investments and leveraged transactions. Smart contracts for transferring assets between protocols and platforms in a fast and practical way are developed through De-Fi.

The main purpose of the De-Fi system is to make the finance mechanism a demographic structure. In this respect, De-Fi offers alternative solutions for people who cannot use traditional financial systems.

How to Earn Income with De-Fi?
The most popular methods of passive earning with De-Fi are lending, staking, liquidity mining, that is, yield farming. Yield farming is based on taking user-owned cryptocurrencies and investing in them.
A portion of the assets belonging to the investors is shared in the liquidity pool. This pool allows distributing funds to other projects over De-Fi protocols.
What are De-Fi Usage Areas?

After the 2008 crisis, the confidence of many people in banks was shaken. Factors such as the ability of governments to manipulate valuations at any time and the potential to print unlimited money have triggered the idea of a decentralized system.
One of the first and most important assets that emerged in this field was Bitcoin. This De-Fi structure, where people can be both users and administrators, paved the way for different De-Fi systems.
Blockchain has made the financial field more liberal; users have gained a system that can safely protect and transfer their own assets. The usage areas of the De-Fi system, which emerged as a rival to the traditional financial system, can be listed as follows.
Decentralized Debt Exchange
Users can connect their cryptocurrencies and other assets as collateral and exchange debt within minutes.
Stable Cryptocurrencies
Cryptocurrency prices change daily and sometimes there are big jumps. In order to prevent this volatility, stable cryptocurrencies have been released.
Their prices are based on nominal assets. The biggest advantage of stable cryptocurrencies is that the crypto value units it provides are free from volatility. This makes dApps and De-Fi protocols more accessible.
Decentralized Exchanges
Uniswap and similar broker-less DEXs give the user complete control over the exchange of crypto assets. Thus, there is no risk for crypto assets.
Decentralized Payment
De-Fi usage areas also include smart contracts. These systems allow making payments in a more secure and transparent way through smart contracts.
Decentralized Insurance
Even if cryptocurrencies are locked in smart contracts, this is not enough to protect them from contract vulnerabilities. Smart contracts cannot be guaranteed to be 100% secure and are always likely to result in loss. De-Fi makes it possible to get decentralized insurance and minimizes the risks in this regard.
Decentralized Funds
Control of return on investment and cash flow is provided by fund management. In De-Fi protocols, passive and active fund management is performed in a decentralized manner. In this way, users can monitor how their funds are managed and more easily understand the cost they have to pay.
Disadvantages of De-Fi System
Although De-Fi emerged with the aim of radically changing the traditional understanding of finance, it is still at the beginning of the road. The fact that it is not widespread enough around the world can be shown among the disadvantages of De-Fi systems.
Users who made a mistake may not be able to undo it. It is difficult for users in regions without the technological infrastructure to access De-Fi systems. On the other hand, in the De-Fi system; There are also liquidity, credit, and market risks. In addition, De-Fi carries legal risks for both project investors and project participants.
For example, it is possible for some people to abuse their lack of regulation for their own benefit. Projects with fraudulent purposes may be developed and some of the users may suffer from these projects.
