Bitcoin Evil Plot?

[Hamguy]

Is it possible to cut off a person or ban them from spending their bitcoins?

Bitcoin to me seems like the NWO Global centralized currency.

And he causes all, the small and the great, and the rich and the poor, and the free men and the slaves, to be given a mark on their right hand or on their forehead, and he provides that no one will be able to buy or to sell, except the one who has the mark, either the name of the beast or the number of his name. Here is wisdom. Let him who has understanding calculate the number of the beast, for the number is that of a man; and his number is six hundred and sixty-six.

Tinfoil hat conspiracy theory ^^

As long as there are nodes and people don't adopt a new version with blacklists then you can spend freely.
Who decides which coins are "blocked"? If you are using coinbase or circle they can do whatever they want.
If major banks adopt bicoin and they decide the Bob and Alice are not allowed to transact with them, what stops them from exchanging their coins for another crypto-currency that the banks do not use? If you have the private keys there should be nothing stopping you from pushing a transaction to the network.

You can try set password on their wallet and don't tell them

[Amph]

it's not even possible with the infamous 51%, let alone with some other attack or exploit

they will end up creating another ripple nothing new, in the end there is no reason for anyone to use a centralized system like fiat, if there is fiat, they just want to take advantage of the public ledger

It depends on how you use Bitcoin. Some people use 3rd parties to store their coins. {Exchanges and wallet providers} These people use their software to block suspicious activity.

These companies can "block" your coins, if they were instructed to do it. {Some people already complained about some of these services blocking them from gambling at certain sites or blocking their accounts}

If you use no 3rd party services, you are fine. {You have full control over your private key}

No.

Actually, theoretically it is.
If someone is to control 51% or more of the network power then they can do it.
And my guess is that when (not if) the time comes where only a handful of corporations (and/or entities) will be left (and able) to mine efficiently we will see things like that.
It's only a matter of time IMO.

Right now, the 51% attack is prevented by the fact that the average Joe is still (kind of) also able to mine and they do it P2Pool.
What happens when it's not profitable (at all) for the average Joe to mine?

Fungibility of bitcoins is very important.
So you really don't have to worry where bitcoins came from. If people were to be stopped from using certain bitcoins, it would destroy the basic concept of fungibility.

In theory all you need to do is to publish a fork where these can't be used. Then you've to see if the network accepts it.

In reality its not going to happen. Bitcoin's value comes from confidence so once this is done the confidence will be gone and those who control the network will have the biggest interest to prevent that from happening.

Global centralised currency is dollar, bitcoin is the global decentralised currency.

[MF Doom]

Bitcoin may not necessarily be the currency you have in mind, but it could be the predecessor to something similar to a "one world currency" where you need this mark to use it. It seems like the technology behind btc could be used for it in combination with RFID technology, it actually doesn't seem too far fetched

have fun

Well you can always go ahead and create whatever alternate currency that you want, problem is, will the mass embrace it? IBM creating a centralized blockchain is nothing different other than seeing another new alternate coin popping out of nowhere and claim that it is far better than bitcoin. We all have our right to own opinion but issue is, will the rest agree to it?

As long as somebody is a free man & has access to the internet you can't stop him using BTC. Countries can try & block certain things but Tor exists, people can use VPN's. Unless you watch over somebody 24/7 you simply can't stop them using or spending BTC. That's the beauty of BTC & it's decentralised nature, people/governments can try & stop us but they will never be able to unless they shut down the world wide web & that is never going to happen.

North Korea is looking at you. It is totally possible to block whole internet and keep people oblivious. You think if government really would want us to stop using bitcoin it still be possible to use?
Imposing regulations on bitcoin is easier that it looks really. Good thing is that regulating this new and not so overall popular tech is not government's top priority.

What happens when a corporate or government entity deploys a quantum computer on the network.

What happens when a corporate or government entity deploys a quantum computer on the network.

The difficulty will increase, if they use it to mine Bitcoin. That said, a while ago someone used the strongest computer in the world to mine Bitcoin and they failed miserably.

This is not possible to stop anyone to use Bitcoin.There are always conspiracy theories about everything which seems to be dangerous for interest of the elite.Bitcoin will make its way by itself as it did till now.This can not be stopped or banned in no way. Bitcoin is successfully resisting all the hurdles and opposition because people have trust on it more than fiat.

You only need to let hearn and gavin go through with their bitcoin xt project. If the community really would switch then bitcoin would be somewhat in private hands. And im sure if government approaches gavin and hearn then its not far to believe they would implement tainting into the wallets. Since they are the only needed to decide what should be implemented.

I hope bitcoiners want give their bitcoin into the hands of these guys so easily.

Yes, will be possible if Gavin and Mike get their way of blacklisting coins.
