A quantum computer can crack ethereum and bitcoin in 1 hour. So now there are many forks that are more protected

How can you say that a quantum computers could crack those cryptocurrencies even though they still doesn't exist yet. Stop making claims unless it is true. People who holds bitcoin will go panic selling making the bitcoin price goes down again.

There are many types of hacking. If the trojanhorse passes in your computer your password, id and username will documented to reached to hackers desk. In these kind of advance ethical hacking and power with the super computers or quantum means it is easy possible to hack the wallet.
If you want secure your wallet, please do not have your funds in online wallet and keep your private key and wallet.dat file much safer in any place.

Of course it is true that no-one can open your door, but it is not true that the house cannot be robbed. The thief can smash the window, pick your pocket when you are on the street, trick his way into your house and so on and so on.
A better analogy would be that you have a house made of the strongest materials known to mankind.  It's entirely impossible for a criminal to break into the house without creating new, vastly better weapons which do not yet exist and expending enourmous amounts of resources in the process.

However, if the person living in the house decides to throw their money outside of the house (spending it) or give it to someone else to hold it (an exchange) or they open up a big hole in their house that lets someone walk through, their funds can be stolen.

Notably, if you have a bank or PayPal, someone can install a keylogger on your computer and take your funds if you input your details.

Similarly, if you expose your BTC private keys (or seed) to the Internet in any way, there's no guarantee that your funds are safe.  But with Bitcoin you can store your money on a piece of paper or an airgapped computer which is never connected to the Internet at all.  Can your bank do that?

I would just like to add that while it can be stolen,  it's only usually stolen through online wallets being hacked and/or scams and wallets on PC's being accessed through a remote access tool on the victim's machine.

Many say that Bitcoin is the safest way to hold value because Bitcoin cannot be hacked. But for many users that is not true.

It depends on how you look at it. Think about this first:

I sell you a door with a lock that genuinely cannot be opened by a thief. I now say that no-one can rob your house.

Of course it is true that no-one can open your door, but it is not true that the house cannot be robbed. The thief can smash the window, pick your pocket when you are on the street, trick his way into your house and so on and so on.

In Bitcoin many believe that because the Bitcoin ledger itself cannot be hacked, their money is safe. That is why they say Bitcoin cannot be hacked.

But it is actually quite easy to steal people's Bitcoin by hacking their wallets, stealing their passwords, hacking into exchanges and so on and so forth. We see it every day.

When you hear "Bitcoin cannot be hacked", many take this to mean that their Bitcoin cannot be stolen.

They are not technically knowledgeable so when they hear the words "cannot be hacked" they believe it menas their money is safe. For them "Bitcoin" is the whole collection of the ledger, the wallet, the exchange, their own computer

Many have their Bitcoin stolen, and therefore for many people they have to stop believeing that Bitcoin cannot be hacked.

For most non-technically knowledable people, the true phrasing is that Bitcoin can be hacked, and is being hacked on a daily basis.
I don't think that you are right because here we can believe in that technology where all the banking system are exists but in actual these banking sectors likes the bitcoin technology more than what they have the technology to handle the public money .
The reality is that we are fully unhackable system of the bitcoin where we can store our money without any limits and issue .
So here I can't think this technology is more better that can be in the current time and no can hack it .

I think this question depends on where you keep your bitcoins. If you store them on cold purses that do not have constant access to the Internet, then you should not worry. If you use online purses, then to the purses can be accessed by the company that provides this purse.

If you talked about the system of bitcoin, definitely I agree that this is impossible to hacked. Because as far as I know those people who build the system of bitcoin are also a hackers, therefore until now technology system used by bitcoin are still improving and develop. They were do this to eliminate those Intruders who wants to steal the idea of bitcoin system.

However if you talking about is the wallet of bitcoin, there's a high possibility to steal your bitcoin, especially if you always broad your personal information. Moreover if you want to secured your wallet don't discuss to everyone regarding that matter. Also the future of your wallet are depending on how you can handled it.

Technology is always updating. Bitcoin and ETH can be exploited and stolen by hackers. I think the most important thing is to have a sense of security. Usually develop good habits of using wallet. Multiple backups, try to use a cold wallet. Hackers are more difficult to operate only when they have done it well.

Yes it definitely is fully not hack proof, but there are ways to prevent it. Hackers nowadays are being crafty doing their things to gain access to our credentials such as phishing sites, trojans and viruses etc.It is all up to you how you take care of it. I think enebling 2 way authentication on both email and wallet is enough.

actually depends on the user itself. as long as the user keeps the key properly, it will be safe. wallet has a high level of security, but if we are careless all will be lost.

I understand the frustration. I always say that there is a steep learning curve with Bitcoin, and there's no exception when it comes to hacks and account compromises.

But really, you're talking about two different things. Whether or not Bitcoin is used as a financial/economic system, people should be aware of how sophisticated hackers are getting. I just had a trading friend (been in BTC since 2013) who recently suffered a hack. He had his hard drive and one of his exchange accounts compromised and lost quite a few coins. I would consider him tech savvy, too.

When old timers talk about putting your coins in cold storage, you should listen. This is what they are talking about...

yes I also think bitcoin can be hacked, security dangers lurk every time in the crypto world.
we must ensure that we register only at global and leading Bitcoin companies, as well as learn how to identify possible Bitcoin fraud.

It is important that we take certain steps for our own security, so that we can avoid possible losses.

There are some basic security measures, among them;
1.Securing an email account.
2.Securing social media account.
3.Use unique and powerful passwords for all online accounts.
4.Enabling two-factor authentication.

Yes, bitcoin can be hacked if you are not securing your all accounts and passwords. Let's be aware of hackers and scammers because they are everywhere and they are not choosing who they going to be victimized. We should be wiser for them. You should not give your private key because It's very important in joining here.

That is why it is really recommended to use hardware wallets to store you Bitcoins rather than using online or software bitcoins that might be really vulnerable to any threats such as spyware and hackers. Phishing sites can be a high-level threats for these online wallets unless you know how to see what is the real site.

You're right, but I think that you make a wrong comparison between the door lock and Bitcoin.
The Bitcoin network or the blockchain can't be hacked, as you would need an enormous amount of hashing power. This can be compared to the lock, that if the lock is not pickable it can not be 'hacked'. However Bitcoin balances can get stolen when an user doesn't safe his funds correctly or when his computer is infected. That's where I think you're comparison is wrong, when funds get stolen because the user doesn't store his funds safely it's actually comparable to door lock that you forget to lock. So it's not really the fault of Bitcoin or the lock but a user fault, in this case I think you can't say Bitcoin is hack-able.

There are talks theat google and IBM's quantum processor can be used to hack the bitcoin blockchain. If it is even remotely possible, devs should be brainstorming to counteract this.
If a quantum computing is fully developed or if it is possible to create one, i heard that rumor many years ago I think it is last 4 years, Some of my professors told us about quantum computer and how powerful it is but the existence is still questionable that day. Now i heard news that they have succeeded on developing a quantum technology that uses a small number of qubits. that would be awesome but not worried at the same time because bitcoin uses SHA-256 that is quantum resistant and any other attacks. I think they called it D-wave.
