If bitcoin had a stable price it would be popular. Even if the price is stable or not the popularity of this bitcoin is not too much popular. Because many people dont know what is bitcoin. Many people dont need to use it. Many people dont have care about bitcoin. However it is not too much popular right now in the future i think this is the most popular coin even if the coin is not stable price.
I disagree, like the other users said, if bitcoin had a stable price, it would not attract people to it. As a matter of fact, bitcoin price is valuable and it must be fought for. It is like gold; worthy and valuable. That is why it is not stable. However, it surely would be popular too. And yes, it will be more popular in the future because more people and more countries will recognize it.
The popularity would surely go down from a investors point of view or for the investors. But the price won't be hundred percent stable, the volatility might get reduced, so the popularity will sill persist, and moreover many uses it as a transaction option, so even if the price becomes stable popularity won't die.
