When a thing is truly groundbreaking, people quickly adopt it on their own - in the last decade no one asked people to adopt smartphones and social media, everyone did it because they clearly saw the benefits.
Sure, but how did people find out about those things in the first place? Word of mouth from current users and advertising. Smartphone producers spend billions of dollars each every year advertising their product. Bitcoin has none of that. Social media spread largely through word of mouth, with people wanting to "add" their friends to their profiles. If we, the current bitcoin users, don't talk about bitcoin to other people and try to spread adoption, then bitcoin doesn't have any of that either. How is adoption supposed to grow in that case?
Adoption isn't announced but it will creep into the system of all without announcement.
I do agree with that, which is kind of the point I am making. We will never have some massive advertising campaign on billboards and TV ads around the world saying "Bitcoin has arrived!", so instead we need slow and steady growth by word of mouth.
Cash is person to person transaction which the government can easily identify where all your money goes just for asking and reviewing all your movements, unlike in bitcoin?
Don't follow you at all here. How can the government easily identify when and where I pay for something in cash? Once I have withdrawn the cash from the bank, the paper trail ends. How does the government know if I give it to my friend to pay for some pizza or if I give it to a drug dealer in the next neighborhood?
