Cryptocurrency Exchange Hacks

Let’s quickly see about the top 2 exchange hacks in terms of Crypto volume in $ lost so far. These exchange hacks tells us the importance of keeping your Crypto safe at all times. If you leave your Crypto in an exchange, it stays in a hot wallet that is like a honey pot for hackers. That’s why, it is not recommended to keep a huge size of crypto on exchanges.

The following crypto exchange hacks highlights the importance of cold wallet

MtGox Exchange Hack

Japan-based cryptocurrency exchange named Mt.Gox went through a severe fall down in 2014. In 2010, a US programmer started this company and sold it by 2011. Soon, in 2013, it became a big player in the world of cryptocurrency handling 70% of all the cryptocurrency transactions worldwide.

Unfortunately, the company faced the biggest Bitcoin hacking incident in history. Almost 740,000 bitcoins were stolen from the customers and 100,000 from the company causing damage of a total of 460 million USD. The company became bankrupt by the end of 2014.


CoinCheck Exchange Hack

Coincheck faced one of the biggest cryptocurrency heists that have occurred around the world. The crypto-criminals hacked the company in January 2018, causing damage to almost 523 million NEMs. Coincheck refused to repay the customers at first however the compensations were made later on.

They repaid all the users in the Japanese Yen. It was then declared that the CoinCheck stored the NEM coins in a hot wallet (wallets connected to the internet) rather than cold ones.

Cryptocurrencies may be relatively safe. However, these hacking scenarios that happened to big companies like Coincheck and MtGox showed how exchanges are always at risk, and the use of a cold wallet to store cryptocurrencies will always be a better and safer option.

Hopefully, with much more research in the future, the Crypto Exchange hot wallets will also become much safer. But, for now, it is better for everyone to move their assets into a cold wallet and take responsibility of securing your assets.

Different Types Of Cold Wallets

You now have all the basic knowledge of what is a cold wallet and how is it created. So, now is the time to learn about its different types.

The cold wallets are divided into 4 different types which are explained briefly below.

Paper wallet

It is a piece of paper on which the private keys and the crypto addresses are printed in form of QR codes. To execute the transactions, these codes are then scanned. In this case, you need to visit a site for wallet generation to create the QR codes.

While the keys are generating, the users are advised to turn off their internet connection or clear the internet history. Once the codes are generated, print them out and make sure the paper it is printed on is not lost or damaged.

If proper precautions are taken, it is almost impossible for the hackers to get hold of the bitcoin private keys and addresses. It is considered one of the best ways to keep the cryptocurrency safe from malware and crypto-criminals.


Sound Wallet

Using a cold wallet does not always mean using a paper wallet. The sound wallet enhances the game of securing a crypto key to a whole new level. It uses a BIP38 encrypted key to convert the data into a sound file.

A sound wallet is your vital key to keep your money safe and protected. In easier words, it is a paper wallet but in an audio form. It assures keeping the private keys safe as encrypted audio files through different devices such as vinyl disks and CDs.

Deep Cold Custody Storage

Deep cold storage wallets have gained quite attention in recent years. Introduced by a London based company, it offers security like a bank vault to keep bitcoins keys safe and secure. So, it is the best cold wallet choice for those who decide to invest a specific amount of money into bitcoin every month, depositing it in the address and never transacting it.

An underwriter is required to ensure the protection and safety through this service. This is a drawback because to provide this service, the address, and identity of the person seeking services is required which don’t leave a chance for those who want to remain anonymous owners.


Hardware Wallet

As the name implies, it is a wallet that keeps cryptocurrency’s keys safe and sound in a hardware device. So, it is becoming one of the preferred methods to keep the keys safe in an offline environment. Pi-wallet is one of the examples of a hardware wallet.

Hardware wallets are virus-protected small devices that can even support multi transactions. They have a really small space apart from ROM to store crypto apps. So, any malicious code will not fit into those devices. Not only that, they even provide the convenience of receiving and sending the virtual currency, QR scan camera, and having a micro storage backup too.


Software Wallet

There are some software wallets out there that allows you to generate seed phrase and store your crypto safely without the need for a costly hardware wallet purchase. These wallets have a good level of security but there are reports of hacking happening in software wallets too.

For instance, there are good options in Software wallets like Electrum and Jaxx wallet. And, there are hundreds of other software wallets. Make sure the downloadable files you use to install and create wallets are safe.

If you are a serious crypto investor, it doesn’t make sense to risk thousands of dollars portfolio by keeping in a software wallet. So, in that case, make sure you invest some dollars into purchasing a hardware wallet.
