is there a way for me to buy the bot with... you know... money? I don't want to give my computer to anyone. sounds like a scam to me....
it sort of is a scam, but most currency is a scam. paypal is a scam, it's just linked itself to banks and credit cards and ebay. paypal is virtual money as well, but it's tied to exchange rates and banks, without their rules or safety nets.
bitcoin, like microsoft points, or wow gold, is a created arbitrary (imaginary) value you can exchange for money or credit or goods. usually one way.
you'd use bitcoins to stay anonymous, and to avoid paying tax when transferring goods with wire transfers. this may be more important in countries like egypt or cyprus or europe with GST/VAT, where euro/gbp prices are insane vs usd, or for buying goods in countries that have region locking like germany, canada, japan or uk, etc.
that said, it's probably:
the worst time to buy BTC due to the rapid inflation,
an average time to create/mine BTC, e.g. due to the difficulty which will increase over time/popularity, a $300 AMD graphics card will produce 0.03BTC/day, roughly $5/day at $140/BTC.
last year, the same card would produce maybe 0.3-0.5 BTC/day, 8 BTC a month. maybe $2/day.
so, apart from the cost of running a gaming PC for a month, it will probably pay for itself in 2 months, that you can spend on games or items or in exchange on sites like mtgox or for goods on bitmit or silk road.
there's other crypto-currencies like litecoin which earn more money (for now) but it's harder to set up.
it's generally a good time to sell BTC, if you think the value will plummet back to $10 = 1BTC after hitting $140 = 1BTC, which it could (somewhat unlikely, not impossible)
if you're ambitious, you can find and use BTC on sites like bitmit.net or the buddy store, but i'd suggest paying with cash/credit at the moment. the delay between buying and spending the coins may lead to losing money.
