It is not widely used yet because not most of the people knows about it even in my country. I think we only got 4 bitcoin ATMs here just in one city i think. Couldnt spend mind in a resto or just in a store
Don't worry with that, the progress continues and in the future we can see more merchants will accept bitcoin.
Right now we have a choice whether we spend it or not but I would recommend be careful in spending if you are looking for a better investment
because just by holding you can already make profit as the value continue to increase.
