It's true that bitcoin have bad reputation in media, mostly because of bad news connected with crimminals.
They are using bitcoin to buy drugs in dark web.
We had a few such stories in my country recently.
So, how to explain advantages of bitcoin?
I will explain it in very simple way.
No government control, decentralized, fast and secured.
True that. In 75% of time i wanted to talk with people about Bitcoin and asked them: "do you know Bitcoin?" They reply: "Oh yes it's the currency of the dark web" or "Yeah, it's used by thieves !". And then talking about how banks, insurance,ect are investing to study about it, they think i am exaggerating. But taking another side and explaining what can be done with the blockchain firstly and how it works, then people start to think a little differently
