In recent times, some new ICO companies have been kidding about Bitcoin on Twitter, Facebook for their ICO promotion. I think this promotion way is very negative for Bitcoin. They showed that Bitcoin will be destroyed and their token will become number one. They have presented it in such a way that the price of Bitcoin will not rise anymore. I think this type of promotion is very negative in the market.
Its all really a marketing technique, a negative one though. By placing bitcoin in a bad light in makes their own coin look more promising. But i doubt that it will be successful. Bitcoin is the most successful coin and is most likely to remain so for some time. Unless their systems work better than Bitcoin and is factually proven its all just useless bashing.
