In my opinion it's important because it allows money to become like air or the Ocean. Something that just naturally exists in our lives (without being owned by anyone) and allows us to value things in our world and store wealth.
I think in the future the value will not be determined by any government but by the world economy as a whole.
The importance of Bitcoin is highlighted from its unique feature that it offers transparency while staying anonymous. It acts as a store of wealth and thus helps in keeping your finance private. Also Bitcoin is becoming important because of the technology which works behind it, known as blockchain technology. This technology is a decentralized public ledger and has many advantages like there is no need of intermediary, has low transaction fees, offers high speed and security and many more.
