You need to improve your account security, your bitcoin wallet. Somehow hackers can install malware on your computer
yeah thats right mate that is the must important to avoid that problem so that no one can manage our account . But there are some stuff now adays around the internet that maybe can force brute our wallet information such as phising link / url link and etc to read all the information involve in our security.so isuggest to becarefull dont attemp to browse if you have doubts on it. Review first before doing anything . Best regards

"Wallet customer care" smells scammy. In actuality you don't need any person to work with your wallet. If you wanna store your BTC really securely, you should use hardware wallets.
It's hard, I know, but you need to get up again and maybe, try to investigate a bit on what happened. Malwares, logging in insecure devices, this all make online wallets the worst way to secure your BTC and should avoid it if you have more than 1BTC. Good luck in future, hope you get back.
Have done the investigation Member.
They called themselves as GDAX customers care and took control over the systems and have done this hacking.
As said lot of shady people around
The case of loss bitcoin so much, we must pay attention to the password security. We shouldn't say the password for anyone, as well as personally related to bitcoin account.
Plus, even if its secured, if hes used any type of wallet with a faulty RNG, its a ticking timebomb. Hence why theres only a few well known wallets that I trust to have a secure RNG.
Quite a few people on here who take security measures like 2FA on online wallets get quite cocky about it, but thats not enough. A good, audited hardware wallet like ledger, an audited paper wallet generator, or a wallet like electrum 2FA is probably one of the of the few ways to keep coins 99.9999% secure. Even then, there is the $5 wrench attack (google it).
Even the trezor hardware wallet had an exploit which helped some soul here recover $30k USD of coins - $3000 bounty to the hacker he paid to help him, a wallet used to secure millions of pounds in coins:

granted, you needed physical access and its been patched, but no system is infallible. Plus i bet there are many trezors out there which hasn't been updated. And this is one of the go-to secure wallets, but very few notices it uses a generic microcontroller.
Best that people on here even those who are 'i told you so' type, should never get cocky. Even I do not, and i use multiple wallets. And now is not a time to get cocky or i told you so when some poor soul has lost £30k.
Even I, a big proponent of bitcoin security had a dumb moment and entered my ledger PIN wrong three times, making good storage of multiple backups of the seed vital. Not counting the time my other ledger wallet somehow became defective, im currently trying to RMA it with them now, but i still have used, and trust their product for years after doing my research.
2FA while good, is not enough on its own, i proved this to a friend of mine with his permission, was easily able to social engineer most places to remove it. Yes, always enable it, though.

That was a valuable info not only for me for all the Crytp holding guys.BEcareful guys,shady ppl and shady activities to steal your digital currency.
hard to know about your loss getting 4BTC hacked is not a small thing as per the current market one btc itself is above 7K and its not a small amount to loose what you have invested . And it is not practical to reverse the transactions as they won't be traces left to find out to which person or account the btc was transferred as btc tech maintain high privacy of its clinets and never keep any kind of personal data of its users so its not at all possible to find out where your btc went its always safe to hold on your btc in offline wallet so that it doesn't get robbed in the future.
I am really sorry for your loss mate

I have not in any way lost my bitcoin because my private Key is always secured...
Everyone are not lucky dude
Even so, online wallet accounts are at risk as they keep your private keys. Even using most online PCs is a risk due to malware. Even with an encrypted wallet, they will lie in wait for you to decrypt, then swipe the private key from memory. The mt gox and the cryptsy situation is an example of this, you should always use a paper/hardware wallet for storing large quantities. I have an electrum 2FA wallet and an android wallet for day to day change, but most of my funds are secured by a ledger wallet/paper wallets. Ledger wallet chrome app is easier to use than most wallet software, all it needs is the ledger wallet be plugged in to sign transactions.
HD wallets with seeds like ledger/trezor/keepkey/electrum also remove the problem of change addresses not being in recent backups, with all keys generated from said seed.
I would say hardware wallets are more secure than unpassworded paper wallets, as you can use them on a compromised machine safely, whereas a paper wallet is ever so slightly vulnerable if you were to sweep it on a compromised machine.

I'm sorry to hear that. Well, what happened to you was also experienced by others. Some of my friends encountered stolen wallet. Truly it's painful and hard to think about it because you did not only lose the money on your account but also the time and effort you had given for a certain period of that campaign that was lost. But as everyone said, charge it to experience and take the lesson learned. All you have to do now in order to avoid stolen bitcoins or hacked account is to take necessary precautions, secure your account's password or private key. If possible, you must be the only one who knows it. Do not share it to anyone or any othe websites prone to scammers or thieves.
I am so so sorry for your loss . Online wallets are dangerous to store long term, as you have found out. I know its difficult, that quantity of coins... I would however for future use recommend the following:
If your using Bitcoin and storing funds you do not wish to lose, consider something called a 'hardware wallet'. These wallets store your private keys within them and can be plugged into any PC, even one with coin stealing malware, and the malware cannot at your private keys, especially with the ledger wallet keeping keys in a secure enclave. Your PC sends the transaction to the wallet to sign it, you can use it even on an infected pc, and it shows the wallet your about to send to on its little screen, and forces confirmation with a button on the unit. Ledger also supports multiple cryptocurrencies, and resembles a USB type stick.
PC or mobile / online wallets are fine for day to day change, but for ultimate security, use one of these, and keep the 24 word recovery phrase safe (i mean it!). Simply plug in, enter your PIN and then you can use it like any other PC wallet. You can load the same recovery phrase onto multiples, this phrase is stored offline, store in multiple locations, or even do what I do and keep an encrypted copy on CD at the houses of family members as well as unencrypted copies in a safe. Great if you forget your PIN or the wallet becomes defective.
Grab yourself a ledger nano s:
https://www.ledgerwallet.com/r/e656
I prefer ledger to trezor, as ledger uses am audited type of secure enclave wheras trezor uses a generic microcontroller as does keep key, both are good though.
Or, you could always use an offline generated paper wallet. In any normal PC or mobile wallet, especially on a PC running windows, keys can be stolen by malware, even when encrypted as the malware waits for your decryption password to be entered. Online wallets can go bust or otherwise be hacked. Great for day to day change, not for your savings. Paper wallets are inconvenient unless being used for long term storage. If your going to generate a paper wallet, use bitaddress.org. Bitcoin being a trustless system, the private key is proof of ownership and funds are irretrievable due to shares consensus rules enforced by the protocol. As long as 51% of the network agrees on rules, nothing can happen other than those rules, and the current network rules are the private key no matter who uses it is the key to unlock the funds.
Electrum does 2FA wallets as well, which are more secure than an online wallet, but in my opinion hardware wallets are the best option, but if you go this road, format your hard drive before setting one up, as you have no idea what malware may/may not be there. Plus, Kaspersky internet security is probably one of the best on the market, in my opinion.
I am so sorry for your loss, I'm always aggressively pushing hardware wallets, as it really is the only way to stop crap like this.
Even if your not hacked, an online provider may be, or in the case of blockchain.info, they had a bug a couple of years ago, reusing a numerical value which is meant to be unique each time a transaction is signed. Someone could view the signed transactions on the blockchain and determine private keys from the public keys using this method, as two transaction signatures with the same r value will leak the private key, a flaw in ECDSA public key cryptography.
Multisig wallets or not reusing the same address for sending transactions will protect you from a potentially faulty RNG when signing but not while generating, although most decent wallets fix this. Or fake wallet sites like the 'coinomiapp' (fake knock off of the coinomi site, do not visit it) will try and trick you into entering your seed etc. There are so many pitfalls, and I think the hardware wallets are simple enough to use for the novice user, and much more secure, provided you don't keep the recovery phrase saved on an online pc
Please grab yourself a hardware wallet for storage, do away with any kind of online/desktop wallet for any large quantity of funds, although I would give an exception to coinbase multisig vaults.
Grab yourself a ledger wallet, store the seed safely in multiple trusted locations, and NEVER have to go through this again. I am so sorry for your loss, £30k plus is no small sum to loose!

Hello Dear Bitcoiners,
Firstly I appreciate the Beautiful Block Chain Technology but after
Have anybody lost/got stollen their Bitcoins due to Fradulent activity and the best ways to get/retrieve them back.However the accounts have been locked but the damage was already done.I got to know that somebody transferred the Bitcoins into an external address only by myself after checking my account which had 0 coins after two hours of the transfer was done,immediately called my Wallet customer care where they locked my account to hold off on the further transactions but thought two hours was not too late to hold off the transaction but it was already done.4.5 BTCs just got off and my heart broke.
When I buy a Bitcoin it takes a week to be delivered into my account but when a fraud happens the transfer went on immediately..Wish these scammers are punished and there is a little enhanced block chain technology to stop these
Any advices/help in this regards is appreciated
But always protect/safe guard your accounts,I would repeat the same message in each of my post as I know how painful it was to loose your hard earned money for some scammers..I would have been happy if it was donated by myself for charity purpose rather being robbed/stolen by the scammers/hackers
I’m sorry for your loss, it is unfortunate that there are so many hackers and scammers and I do not think things are going to improve if bitcoin becomes more popular since at that point there will be a lot more money to be made for those criminals, the only thing we can do is to secure our coins to the best of our ability, this is why I’m very paranoid when it comes to my bitcoin and I take all the precautions necessary to protect them from those thieves.Firstly I appreciate the Beautiful Block Chain Technology but after

..All these messages are making feel better and strong and to make sure in case if iam back into trading to be more secure.Sorry to hear that you lost your hard earned money. Let this be a lesson for everyone who uses online wallet.
Online wallet should be used only when you need to exchange or trade the coins. You are not supposed to store your coins in that.
Next thing is always use unique passwords for your wallets . If you think you will forget the password, then store it somewhere safe.
If you use same passwords in all websites you signup then its really easy for scammers to hack your account.

Yeah,sharing each others experiences makes others to be more secure and gives a reason to be more protective with their wallets.So please share more and more advices guys !
Improve security..use different accounts.Don't keep all the eggs in one bucket.Divide you money.
Interesting topic.. I've been wondering more about this and how to protect myself.
