Bitcoin isn’t that much different to a few of the recognized coins, it is simply put 'The Godfather' of Crypto currency.

It is the leader in the crypto space, if you do a bit of research you will see that usually whatever Bitcoin does, the other coins follow suit.

The reason Bitcoin is attacked more so than the other coins is because the Bitcoin haters out there, or the non-believers, know that if they attack the leader then the negativity will automatically spread to its followers.
