# The Problem

**Sustainable Construction**

Today, we are speaking more and more about sustainable methods of constructing buildings, renewable energy sources to replace fossil fuels, and so on. However, there is still a lot to be done if we want to truly mitigate and roll back climate change. It is a well-documented fact time is running out for our plant and all of us have to come up with new and innovative ways to tackle this global problem. Big Time believes that Blockchain technology has a big role to play in this and want to be the advocates of this change.

**Centralized Financial System**&#x20;

The problem with a centralized financial system is that all of the powers are vested with a single authority or group of authorities. They control the system and can make changes as they please. The economy depends on the decisions of policymakers.

**Inflation** is one of the major problems associated with the Fiat system. This means that Governments can cover deficits by printing more money and inflating the currency supply. What this actually does is bring more currency into the market, inflating the market, and, in turn, devaluing money.

**Decentralized Finance**

Decentralized Finance came as a solution to this problem, allowing people to connect with each other in a peer-to-peer fashion and access various financial functions.

Although Bitcoin started the wave of decentralization, DeFi took this a step further by allowing even the unbanked the opportunity to access these services.

In theory, this is true. But the reality is far from it.

For one, decentralize finance is still relatively a new term to even an average crypto user. To make a profit or access the financial functions that DeFi has to offer, a user has to have a certain degree of technical knowledge.

For example, yield farming is a great way for users to generate passive income with their crypto tokens. But for yield farming to be profitable, they have to apply different strategies. And these strategies are not easy to come up with. This is the reason most people entering DeFi do not make a profit. All they can do is invest in a DeFi token and hope for the token price to increase.
