Haha good funny pal, Bitcoin is not for groceries why just it is for more expensive stuffs so why would it would be just use for groceries. We can say that in one side if we are poor right now we cannot effort groceries daily in our life after investing in bitcoin and getting a lot of income from bitcoin so we can daily buy groceries in our daily life. So I was saying that bitcoin is using for every purpose not just for a small purposes as you mentioned.
