A lot of people are arguing over this nowadays. There's debate between this and that economic school, between politicians, between programmers. Don't listen to all of them. Some people are smart; some are misinformed. Some say the system is worth a lot; some say it's actually worth zero. Some say it's digital gold; some say it's a currency. Others say they're just like tulips. Some people say it'll change the world; some say it's just a fad. Research and you'll be okay.
