If bitcoin has enemy (except altcoin) what is it?

Bitcoins worst nightmare would be a crashdown of internet and power.

I agree with you. without the internet and energy that exist on this earth, bitcoin will be paralyzed. besides, people who use bitcoin for crime make bitcoin image bad.

The biggest enemy of bitcoin will be the government and bad media. The government will try to control and manipulate bitcoin so that they can gain profit on it and mad media causes FUD on people causing them be afraid that they might lose their money on bitcoin causing them to sell their coins making the price go lower.

the media and the government can be the enemy for bitcoin but they are not the real enemy because sometimes the media wants to make bitcoin down in a moment so they can buy bitcoin at cheap price. and the government itself can not control bitcoin but i am sure that the government is agree with the bitcoin concept which can help every people to solve their financial problem. and i think the enemy of bitcoin is the weak hand person that trying to selling their bitcoin when the price is make a little correction for the price and that person don't want to get loss.

I think the worst enemy is the bankers, crypto will be the end of banking, as there will be no need for them, thank God for that, The bankers are the biggest criminals in the world.

Maybe you mean banks? cause banks and banking has big difference. Bitcoin offers banking and more whereas you control your own money. Whereas banks is a third party intermediary thus saying crypto will be the end of banking is entirely wrong. I say cryptocurrencies revolutionize banking whereby these traditional banks are no longer relevant to conduct commerce.

In my experience i think there's only their enemies exist in this world. First one is china after the ban on ICO the price fall down. Second is JP MORGAN  third and last one is Bankers. We all know how Crypto is destroying bankers and banking sector does like this digital form of currency. I think Bitcoin has to face all these hardles and is coming out good as you can again see the all time high price of 5200$ today.

Bankers are the enemies of bitcoin forever.They consider bitcoin as their main rival.They try their best to destroy bitcoin.

Governments come under the second category.They just don't want bitcoin to progress more and so they take actions to ruin its progress just as china is now doing.

In future,quantum computers may become the worst enemies of bitcoin.It is said that they would be able to read the private keys of our bitcoin wallet with the help of public key itself.It will be a serious threat to bitcoin.
