I introduced Bitcoin to many friends, its not that everybody doesn't likes it, its like they are not interested.
Those who doesn't likes it, I simply ask once the reason, and then try again to show the potential of Bitcoin.
I think the main reason that people don't like bitcoin is the bad explanation. There is some people they can't introduce how bitcoin is it with a good ways, so people who listen, they don't care about this topic, so they will be not interested. In other way, I like to know the reasons and open a good discuess with them.
It does not necessary has to be a bad explanation, I think this is not the most important reason.
The thing is that we are having issue with people that are just not interested about cryptocurrencies, so in my opinion you cannot do anything about it: you won't force them to buy bitcoins, right?
It is just only their free will to start educating about BTC and altcoins, nobody is going to tell anyone else what to do.
To be honest however, i think that many people may change their mind, in the moment they hear that you can make additional money on bitcoin without much effort taken. It is all about skills (depends what are you good at) and creativity (unless you are some kind of a freelancer).
