I think you don't really get the purpose of how bitcoin works. And one should use Bitcoin in our daily purchases maybe in the future but as of now and especially you libe in the third world country, it'll be difficult to suffice your needs by using bitcoin in your daily needs. Not all restaurants or any grocery store accepts bitcoin yet.
And besides, why do you even need bitcoin for buying goods if you can exchange it into cash and buy whatever you want. The only thing that matter here is as long as you can transfer your bitcoin to bank and make the full use of it that is okay. Bitcoin is for digital services only I think that is the best way to maximize he use of bitcoin.
