Decentralized Finance in short has got a big meaning within it. For users who have been a part of cryptocurrency investment it can be understood. This is just a platform developed over a blockchain with which one can develop his own financial tools and products to decentralize the investment. For example when we deposit into a bank, we'll get mere interest while the bank receives high interest spending our money on different other shares and loans.

Through Defi this is being eliminated, because everything is open and we used to create our own tools and make the investment. The perfect functioning will happen when the exchange services too go decentralized.
