why you talk about things 2 years ago?
I don't think that Monero would replace bitcoin any time soon. Monero would need the same amount of press coverage that bitcoin has right now considering that most stores may have not heard of it.
Many big, popular stores haven't heard of Bitcoin either. A good option to make one or both popular is to ask everytime we go somewhere to eat or buy anything if we can pay in the respective currency. People will ask each other what is it and this is how Bitcoin can get easily popular.
