If I give you something valuable I want something valuable in return.

Now we all know what you want me to give up for bitcoin: food, water, property, services, laptops, internet, jewelry. With water I can quench my thirst, with food I can feed my family, in property I can live, with jewelry I can surprise my girlfriend etc.

Thats the PRICE of bitcoin (at least for today).

Now what do you give me in return?

What can I do with a bitcoin once you have transferred it to me?
