but mostly I have to withdraw because there is a need in the real world
Where do you withdraw 1 btc, because nowadays the fees are high until you get the cash.
It really depends on your country. There should be a local exchanger around your country or if not, you can just get cards like on my signature to withdraw to your ATMs
Well the best thing is to use your bitcoin instead to have to cash it out.
In my country (Netherlands) I can use my bitcoins to buy everything and when I say everything I mean everything.
Even pay my bills with bitcoin because there is a service for it.
You should try and focus to make sure that you local stores accept bitcoin so you can buy food, drinks and clothes with.
There is no service for it in your country? Sounds to me there is a oppoprtunity there for you.
Regarding exchanges we have tons of them in the Netherlands.
In the Netherlands Bitcoin, Guldencoin and Digibyte are big and growing everyday because the community is actively going to stores and actually using the coins instead of holding and cashing them out for worthless fiat money
