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.
