Then there’s another way: take over the communication channels. Create bots to argue with anyone who disagrees with you. Make them feel alone. Make them feel stupid. Ban anyone who can make an intelligent case against you. Nobody will speak up because nobody wants to be banned themselves.
Call these people or companies ‘enemies of Bitcoin.’ Attack their character and reputation. It doesn’t even matter if what you say is true, so long as people can believe it might be true. The mobs on Twitter will do your work for you.
If they try to make their own coin to compete against Bitcoin, call them scammers. Even better, pump and dump the coins they created so you can buy more Bitcoin, all while telling the mass of people it is evil and immoral to buy these ‘alt-coins.’ We don’t need to follow the rules we set for others.
