How old is DeFi?

Ah, an intriguing question indeed! When it comes to the age of DeFi, or Decentralized Finance, it's a relatively young concept that has gained immense popularity in recent years. While the underlying blockchain technology has been around for some time, the concept of DeFi as we know it today is a relatively recent phenomenon. So, if we're to put a number on its age, DeFi can be considered a teenager in the grand scheme of finance. It's still in its formative years, evolving rapidly, and pushing the boundaries of what we thought was possible in the world of finance. But despite its youth, DeFi has already made a significant impact on the financial landscape, and its potential for growth and innovation is seemingly limitless.
