It will still be popular even if Bitcoin had a stable price. Most companies and retailers don't accept bitcoins today due to its price instability. They all would start accepting bitcoin as payment if its price would be stable.So, there will be a huge increase in demand for bitcoins which would increase its price and help the progress of bitcoin , but since bitcoin is a decentralized currency, its price changes way to often based on the increase and decrease of demand .
Bitcoin will be both popular and popular, but only in certain circles. As though I did not want it, but not all people can use crypto currency.
You cannot expect all people will use bitcoin, it simply just not gonna happen, potential user are those who are
educated with the online world and they have tried transacting online. It is very risky for the uneducated people and it
will take time to educate them and will not ensure if it will succeed.
You are completely wrong, studying or getting educated for bitcoin doesn't take a lot of time because bitcoin is very easy to understand and easy to use, it is just like a money with a lot of advanced features unlike the traditional money so people will get used to bitcoin for a very short time and it will just take them at least 2-3 days to understand bitcoin or even one day to fully understand it if they really putting a lot of attention.
