A “Debt Management Plan” which outlined plans and potential refunds for victims. The exchange never managed to get the money back from the hacker.Poloniex ($64 K)According to Poloniex owner Tristan D’Agosta, on 4 March 2014 97 BTC was stolen in the following method: “The hacker discovered that if you place several withdrawals all in practically the same instant, they will get processed at more or less the same time. This will result in a negative balance, but valid insertions into the database, which then get picked up by the withdrawal daemon.” This was estimated to be around 12.3% of the total BTC on the platform and the company has since reimbursed its customers.Mt.Gox ($600 M)The victim of a massive and prolonged hack, Mt. Gox lost about 740,000 BTC. An additional $27M was also missing from the company’s bank accounts. 200,000 bitcoins have since been recovered. Investigations revealed that the hack may have begun as early as September 2011. Prior to September 2011, Mt. Gox’s unencrypted private key appears to have been copied. The hacker(s) used the file to access and gradually steal funds associated with Mt. Gox’s private keys without detection. The shared keypool led to address re-use, with the Mt. Gox systems misinterpreting the transfers as deposits being moved. Whenever the wallets emptied, Mt Gox credited an additional 40,000 bitcoins to multiple user accounts.2013PicoStocks ($3+ M)Second attack in one year caused this exchange to go bust. This time a total of 5,896 BTC were missing from both its “hot” and “cold” wallets. Because cold wallets can’t be accessed in online attacks, the theft was most likely an inside job. The amount in dollar value was not shared, but in November 2013 the bitcoin price jumped from $199 to a whopping $1100, so it is hard to put a figure on this theft. I estimate it to be upwards of $3,000,000.BIPS ($1 M)Hackers launched two DDoS attacks to overload a Danish Bitcoin payment processor and free online wallet service BIPS’ servers. They gained access to several online wallets, allowing them to steal 1,295 BTC worth over $1 million at the

102,101 BTC loss, amounting to approx. $688,845 being stolen in total.On March 1, Linode, a web hosting provider whose clients included Bitcoinica, was hacked. The unknown intruder successfully stole 43,000 BTC (approx. $228,845 worth) from Bitcoinica.On May 11, attackers used a compromised email account to lift 18,500 BTC (approx. $87,000 worth) from Bitcoinica’s hot wallet.On July 13, another attacker gained access to a LastPass account containing passwords needed to access the MtGox account. The LastPass account used the same password as the MtGox API key used by the Bitcoinica server when Bitcoinica was still live. The attacker withdrew 40,000 BTC and 40,000 USD (approx. $350,000 in total).2011Bitcoin7 ($30 K)On 5 October 2011, Bitcoin7 exchange reported a theft of 5,000 BTC and shared that attacks originating from Russia and Eastern Europe targeted Bitcoin7’s server, compromising wallets and user data. The exact amount of this theft is unconfirmed but it comes to roughly $30,000 as BTC was around $6 at the time.Mt.Gox ($400 K)In June 2011 a hacker got hold of Mt. Gox exchange auditor’s computer and changed the price of bitcoin to 1 cent. Then the attacker started buying bitcoin at this artificial price using the private hot wallet keys of Mt. Gox customers, obtaining about 2,000 bitcoin. The hacker managed to steal around 25,000 BTC (roughly US$400,000 at the time) from 478 accounts. In 2014 the exchange suffered another major exploit that ultimately caused its collapse (see above).Related Posts: Crypto Hardware Wallets (Reviews and Guides) Over the years I have reviewed and created tutorials on the top hardware wallets to help you with choosing the one that is most suitable for you and also, with setting up and getting started with these devices.

If you’ve left these coins in the same place where you bought them, I have news for you:

Bitcoin, the pioneer of cryptocurrencies, has become a significant asset for many investors. As its value continues to fluctuate, the importance of securing your Bitcoin cannot be overstated. This article will provide a detailed guide on how to save your Bitcoin, ensuring it remains safe from theft, loss, or unauthorized access. We'll explore various methods, real-life examples, and expert advice to help you make informed decisions.Understanding the Importance of Bitcoin SecurityBitcoin is a decentralized digital currency, which means it is not regulated by any central authority like a bank or government. While this decentralization provides numerous benefits, it also places the responsibility of security squarely on the shoulders of the user. Unlike traditional currencies, once Bitcoin is lost or stolen, it is nearly impossible to recover.Why Security MattersIn 2014, Mt. Gox, one of the largest Bitcoin exchanges at the time, filed for bankruptcy after losing approximately 850,000 Bitcoins, worth around $450 million. This incident highlighted the vulnerabilities within the Bitcoin ecosystem and the critical need for robust security measures.Types of ThreatsThere are several threats to Bitcoin security, including hacking, phishing, malware, and physical theft. Each of these threats requires specific strategies to mitigate risks effectively.Choosing the Right WalletThe first step in securing your Bitcoin is choosing the right wallet. A Bitcoin wallet is a digital tool that allows you to store, receive, and send Bitcoin. There are various types of wallets, each with its own advantages and disadvantages.Hardware WalletsHardware wallets are physical devices designed to store your private keys offline. They are considered one of the most secure options for storing Bitcoin. Popular hardware wallets include Ledger Nano S and Trezor.Example: In 2018, Pavel Lerner, a prominent cryptocurrency analyst, was kidnapped in Ukraine. He was released only after paying a ransom of over $1 million worth of Bitcoin. If Lerner had stored his Bitcoin in a hardware wallet, it would have been more challenging for the kidnappers to access his funds.Software WalletsSoftware wallets are applications or software programs that you install on your computer or mobile device. While they offer convenience, they are more vulnerable to hacking and malware compared to hardware wallets. Examples of software wallets include Electrum and Exodus.Paper WalletsA paper wallet is a physical document that contains your private and public keys. While this method is secure from online threats, it is vulnerable to physical damage or loss. It is crucial to store paper wallets in a secure location, such as a safe or a safety deposit box.Online WalletsOnline wallets, also known as web wallets, are hosted by third-party providers. They are accessible from any device with an internet connection. While convenient, online wallets are the least secure option due to their susceptibility to hacking. Examples include

Bitcoin Symbol in a 3d illustrationgettyWhen you buy bitcoin, ether, or any other asset on an exchange, oftentimes you are not actually getting crypto.Instead, you receive a promise or IOU. Essentially, you become a creditor to the exchange or broker. It is a similar setup to opening a savings account at a bank.The only way to know for sure that the crypto exists is to withdraw it from the exchange and place it into a private wallet that you control. Unfortunately some investors have learned this lesson the hard way following high profile collapses and bankruptcies this year of companies such as FTX, BlockFi, Celsius CEL , and Voyager.You might have heard the phrase “Not your keys, not your coins”, meaning that if you don’t personally hold your own private keys, you can’t be sure that you have full control over your cryptocurrency. This is an important phrase to remember so that you understand the fine print of buying crypto from a centralized entity.Does It Matter?It can. Most investors are more concerned with getting exposure to bitcoin and other digital assets than actually holding it themselves. This makes perfect sense, as it is a true bearer asset with little recourse if it goes missing. Plus, the technological hurdles to holding your own crypto, let alone getting involved in other activities such as lending and staking, can be intimidating. Anyone who has purchased shares from Grayscale, invested in SkyBridge’s Bitcoin bitcoin BTC Fund or any other crypto ETP made a conscious choice to pay a fee for someone to procure and safeguard the crypto.That said, many people have either knowingly or unknowingly adopted a similar mindset when purchasing crypto from popular exchanges and services such as Coinbase, Gemini, Kraken, Square, PayPal, eToro and a host of other services. They want convenience, value the websites and applications that look and feel like mobile banking or trading services, and trust that their regulated nature will ensure that the platforms operate honestly. They have faith that when they go to withdraw their coins, the funds will be there.What Are The Risks To Not Controlling Your Keys?The risks manifested themselves this year with all of the bankruptcies mentioned above. The millions of unlucky creditors to those firms may be forced to wait years for restitution, and they are likely to only get a pro-rated portion of their assets back. For a point of reference, creditors to Mt. Gox, the original crypto exchange that had 850,000 bitcoin stolen from it in 2014 before declaring bankruptcy are still waiting for their own payouts.Additionally, exchanges do not carry FDIC or SPIC insurance, and each one has a separate restitution policy. Some have a rainy day fund created with
