[Bobcrypto]

The reasons Decentralised finance (Defi) is importance is simply to brings the transparency and security of distributed ledger technologies to traditional finance use cases, while reducing inefficiencies and solving pain points. Defi intended to migrate from the current infrastructures to more robust, secure, and efficient systems.

The fact is that centralized finance provides new opportunities for all users to make independent payments, as well as for those who previously refused to cooperate with the banking system.

The centralized system AKA government system hasn't been working since its creation, their gathered wealth are all about favouritism and nepotism which led to the creation of Bitcoin as Decentralized assets without middle man, you dnt need anyone permission to sent value or equity to any one across the world.
With the emergence of decentralization, Borrowing and lending has been made easier. Imagine borrowing without any other third-party or middle, just communicating with a computer and you get what you want. Isn't that unique and economical with low charge and fees.

That's all right. The main task of all governments is to take into their own hands and control all the financial transactions of every citizen. Cryptocurrency is the collapse of the financial foundations of many states. Now we see that many countries are beginning to take cryptocurrencies for granted, as one of the financial instruments. This is the future, and it is inevitable. Fiat money is slowly turning into an unsupported "paper".
