You gotta be careful trying to spend too much time trying to persuade others to buy bitcoin when they do not understand and/or appreciate bitcoin's investment case irrespective of what you are doing yourself and what you are telling them. In their minds, they believe that you are the crazy one.
Yeah, it might sound a bit harsh, but it's pretty silly when we try to convince others, especially when it comes to investing. Nobody can predict the future. We're actively involved in the market, which makes us believe in the potential of Bitcoin and cryptocurrencies as the future. However, many people outside this market don't even understand what Bitcoin is, so how can we expect them to have faith in it? Those who want to understand will do so on their own. Trying to persuade others to believe in our views is just a waste of time and not very wise.
You are absolutely correct. Yes, if someone does not accept Bitcoin and does not want to get bitcoin knowledge, anything the persuader is telling the person is a total waste. Sometimes they act like they really care while listening, but after listening they don't partake or even make an attempt to take advantage of Bitcoin.
It's a foolish idea to try telling someone who isn't interested to investing in Bitcoin about Bitcoin, because after everything, some of them still don't give a fuck, so I do suggest we should wait for them to come to us first before telling them about Bitcoin, or they should make a move to have Bitcoin knowledge first before we can give them a chance of tutoring, but trying to persuade them first will not be a good start and will look like forcing them to do what they still don't won't and trust to be told, inside their mind the persuader is a crazy fellow who is forcing them to do what they don't want or like.
