everyday, bitcoin haters are viruses that can make weak bitcoins price. and even if we are not attacking them, then they will look for opportunities to make bitcoin die, because they do not like the presence of bitcoin. and all we have to do to shut up them is by making a good contribution, spreading the benefits and functions of bitcoin to the public, so when bitcoin haters spread FUD, the public will not be easily influenced, because we have changed their mindset about bitcoin.
The only thing that we can do is shut up and do not listen to them. Some people just wont realize their mistakes until its too late. Let them say anything. Some of them just dont have enough knowledge and been joining scam program so they think cryptos are like pyramiding scheme. But do not be like them. Some of them are following the wrong people and fake news from the media. It is hard to convince stupid people. A lot of those "SOME" for sure have tried using bitcoins but failed to make profits from it.but lets just respect those haters point of view about cryptocurrencies and focus more on developing ourselves and making profits from it. Just pray for them, hahaha.
