Re: Bitcoin is not only for criminals/bad people and get rich quick!
Some may disagree, but if you mention the word Bitcoin somewhere outside this forum, those who have heard something about it will probably have some bad associations that will be associated with various financial frauds, ransomware, the term fake money or even the claim that Bitcoin is responsible for climate change (due to mining).
An online friend recently asked me if I know bitcoin and I said yes. He then asked me if I joined bitcoin and I was like wuut! 
I laughed at the other things he said after that (he was talking about some investment scheme) but I still ended up explaining to him that bitcoin not a company and that he doesn't have to join any group and invite people to earn. I hope he was able to learn from our discussion.
It's a fact that some ignorant/uneducated people are quickly drawn to quick income and there are those who takes advantage of that using bitcoin's popularity.
