They are not to blame when the price of bitcoin drops, some bitcoin haters create such a gloomy situation with their articles and comments that everyone gets panicked and most people start thinking that the price would drop even further.
The purpose for those haters is also to buy at the price OP mentioned, that is why they create FUD that might cause crashed price, but unfortunately for them, it is already too late, now that they cannot buy for that again, they are trying to create FUD for $4500 which will still not work.
As it is now, bitcoin is not ready to follow the down trend path again, I think the bulls have successfully killed the bear and any bear that may want to rise up now is not yet born. So, let them continue with their FUD till they miss out, we most always have people that will stand as example to other in future. So we need them.
