Re: If Bitcoin had a stable price, would it still be as popular?

I personally think it would be even more popular, since people would be able to convert fiat to Bitcoin and hold them without having to worry about it losing value.
It would be used more as a real payment method than it is now.

agree. people are afraid of the non-stable price that will risk their money to lost. besides, bitcoin is easy to be used, so it's possible to bitcoin to be more popular

Price instability in bitcoin price attract more people to bitcoin and hence more buying and usage.If bitcoin price were stable it would have been much attractive investment option and people would not have bought it

It might become uninteresting for the speculators. I agree that most people buying bitcoins today are speculators and long-term investors. But what about other (For eg. those looking it bitcoin as a pure payment means)?

If you don't want to get exposed to the volatility when using Bitcoin as currency, then you can choose to convert fiat to Bitcoin at the moment you want to purchase something with Bitcoin. I also do it this way.
