What purpose does bitcoin serve?

I know little about crypto so don't take this as an attack, rather someone genuinely curious to the benefits of bitcoin within our society.

Most people I see on reddit praise bitcoin for being the future but fail to fully articulate why. I hope everyone prospers and lives they're dream life; but I don't see why bitcoin would be the future currency.

Anyone can see its worth a lot of money, but why? and what future does it really hold in our society?

Please enlighten me.

Edit. I've been enlightened and got the answers I was seeking, I'll do my own research going forward. I appreciate all who gave their. Good health and good fortune to all!
