I do not know which companies are scared of bitcoin and other cryptocurrencies. The only thing I know that there are many companies working to learn and make their own cryptocurrencies. I think that the cryptocurrency give people new chances and opportunities
Those who are scared of crypto currencies must be loan or insurance companies I believe. Otherwise others dont need to fear this technology at all rather they can make millions from it if they give their customers choice of clearing all bills in bitcoin. May be those who are involved in keeping data of people are panicked because bitcoin is giving people an authority of keeping their transactions totally private.
