The last year's news about bitcoin reaching 20,000 $ made it very intriguing and interesting for people to buy and invest on. I think it's safe to say that bitcoin is a controversial product since it sparked different controversies and issues regarding its legitimacy and viability in the market. A lot of people took sides and now there are anti-bitcoins just as like there are pro-bitcoins. If this was not controversial enough for you I don't know what will.
