If bitcoin has a stable price around 1000$ it will become more popular but if the price has fall down to less than 1 $ i think everybody will try to look for another coin to replace bitcoin
No to be honest I think that it will not be as popular because the most people are using it because they want to make money so they use it as an investment.
Bitcoin will only be popular when the price will become more stable, the price now that is fluctuate hard is only good for the investors or the traders but would not really help to adopt more people to use bitcoins, the best feature should be the fast transactions and the low cost.
I can say it will be more popular because many oppurtunities will be open for bitcoin if price will be stabilized many advertiser will come and maybe we cn see more sig campaign will be open for future, and i can see thay price stability is better than flactuating price is because if price is so high like today we cant really see newly open sig campaigns and also advertiser will pulling of since they cannot shoulder the fee
