Do you think if BTC had a stable price which could only be altered by $0.01-0.10 it would still be as popular and as used?
Obviously not, there are already a lot of coins with different values even higher then what you mentioned about what if bitcoin would have been and they are not as popular as bitcoin because bitcoin has increased its user database by the growth of its price otherwise it wouldn't have been so popular in the world and it grows that is why it attracts people.
We cannot say that bitcoin is very popular at a moment and it has reached everywhere but its gaining popularity and many new people are joining the community which is really a good sign.
