I hope by 2020 that alot more places start to get involved with the bitcoin.
Yup things will change as time passes and bitcoin will also become more popular in coming years and we will witness increase in the adoption level, but not sure when will find physical shops to spend them.
We couldnt say that we cant see any shops that accepts bitcoin as payment but we could say that it will be stores not many that accepts bitcoins as a payment. Unlike now i couldnt see any from our country that accepts bitcoin as payment but hopefully soon! We could see a store that accepts bitcoin when we buy food or stuffs
It will depend on the adoption level of people in any particular country, if there are more active users of bitcoins then it will make it easy for merchants to implement bitcoin as a mode of payment in their stores.
