Now I use bitcoin for investment only. I have few coins, so I do not want to use them to buy pizza or coffee. I am hard working for them. I better leave them for the future.
You could use before to buy pizza , coffee etc with bitcoin but now the transaction speed is really slow and fees has also increased. So it is best to use bitcoin for investment purpose only.
For such small purchases it is very unprofitable. Perhaps in the future will improve this system that will allow you to make purchases in any country in the world. For now, you just need to wait for the growth of coins and accelerate the conduct of transactions.
