I'm sorry if I offend. Its important to realize that "getting what you wanna" can be done with whatever you wanna. Maybe an example would help. Can you tell me something you can't get with gold or bitcoin or bags of rice? I'll call the guy you want to get that thing from myself and determine a price in all three of those. To be fair, sometimes it is quicker to go through a local intermediary fiat dealer, if you have a good one, than to talk with people.
You mention that your family isn't rich. I interpret that as being that you have grown up using counterfeitable units and assuming they are "money" and as a determination of who is rich or not. Kind of the definition of poverty. Escaping that is up to you.
I know we can exchange our bitcoin to get anything we wanna,what im saying is that you cant pay with bitcoins direct the same way you do with fiat,anywhere you go fiat and card is the option ,you cant use bitcoin .I didnt get offended i know how hard is to get the things we eat,atleast some of them,the kind of work no one wanna to do and dont respect who work there.
