Please do not feel guilty about wanting to make money.

Some people are early adopters, some people are late adopters. You want to use Bitcoin as an investment, but not as a lifestyle. This makes you an early adopter of the technology but not really an early adopter of Bitcoin as a currency. It's not a big deal. Everything has some kind of odd subculture around it, you're not required to participate in every aspect. The biggest reason I am into Bitcoins is because I want to make as much money as possible.

Although if I were you, I would save at least some Bitcoins, indefinitely. You don't know what will happen. Maybe the value will rise to 1000, who knows.
