I agree with others said here, those who wants to destroy bitcoin are the scammers, bitcoin competitors. Also, who dont like to use bitcoin because of others difficulty to use it. I think these are the things they like to destroy btc.
In addition to competitors, it is useless to destroy bitcoin. Users on the contrary are interested in its constant development.
They are thinking that bitcoin in very wrong way. Some people are saying that bitcoin is illegal and used by terrorists. This is the reason many people trolling the bitcoins without proper understanding.
Actually bitcoin has the potential to grow more in chart. many people running behind bitcoin, so no doubt is no need to troll at all. this is for destroyers and trollers.
All that is distributed on the Internet and carries with it negative consequences regarding the crypto currency, someone is profitable. I can not understand This reason, But these users really need to troll.
