All of them admitted there's no perfect solution to the problem. In the age of cryptocurrency, hard drives and personal computers have become the new bank vaults. And our real-world knowledge of protecting money from theft is not enough in the virtual world. The following suggestions can serve as a safety pamphlet for new cryptocurrency investors.
Before you open up an account on Coinbase [or other exchanges], set up an unique email that you are going to use for that account. Make sure to set a really hard and long password, and you are the only one to access it from a piece of paper that you control. On Coinbase, turn off SMS-based two-factor authentication and account recovery for your email account. If you move to Google Authenticator but don't turn off SMS account recovery, a phone port attack can still lead to an email compromise.
Sean Everett, VP of product management, Coinbase account was hacked by phone porting attack. Call your cellphone provider, put every level of security you possibly can, and add a passcode to it. The next level protection is to add a "do not port" SIM card to your account. That can last for a year. Even though Coinbase says it takes security seriously and has system designs to protect customers, it's not a bank. Don't trust it as such. Don't keep all your cryptocurrency investments in one place.
Diversify among exchanges. It's unlikely you are going to get hacked at the same time through all of them. Especially if you have different emails and passwords for each. Sanjay Beri, CEO of Netskope , specialize in enforcing security across cloud applications and network.
Think about "hot wallet" as a checking account and "cold wallet" as the savings account. Then, take a computer, reset it to factory setting, disconnect it from the internet and keep it offline.
Last, load the cold wallet application onto the computer, keep your cryptocurrencies on that clean and offline computer. You can make transactions offline, using the cold wallet application. Amir Bandeali, CTO and founder of 0x project. If you must use a centralized exchange, withdrawal often, store your tokens on a hardware wallet, which is a hardware device, creates transactions without connecting through the internet.
If you are trading tokens on ethereum, I recommend looking into decentralized exchanges. Encrypt your hard drives and mobile devices , and make regular backups of them.
How can you best safeguard your cryptocurrency holdings? The answer lies in the private key, a bit number that unlocks a cryptocurrency wallet. That sensitive data, that investment, is all tied up in your private keys. You need your private keys to spend your bitcoins, so if someone gains access to your private keys, they can and will spend your bitcoins, and your bitcoins will be lost to you. The address is another number, derived from a private key, that establishes ownership of a unit of bitcoin.
Once you ensure that your private keys have a layer of protection, you need to safeguard your cryptocurrency wallet. A wallet is both a collection of one or more private keys and the software you use to interact with the cryptocurrency protocol.
It is rare to hear about wallets being compromised if the private keys are not stored online somewhere. To trust cryptocurrency exchanges requires an understanding of how they work. There are two different types of cryptocurrency exchanges. A centralized exchange means that you trust the exchange with your cryptocurrency funds and your private keys, and you trade with the exchange for what basically amounts to IOUs.
You allow the exchange to manage the security of your funds on your behalf. That can be beneficial if your own computer gets hacked or its hard drive dies, but it also makes exchanges prime targets for cybercriminals.
Centralized exchanges let you withdraw units of cryptocurrency and convert them to dollars or other "real" currencies, and also transfer units of cryptocurrency to your own privately held addresses of bitcoin or other cryptocurrencies. The exchange will generally charge between 0. Decentralized cryptocurrency exchanges allow for simple and direct peer-to-peer trading of cryptocurrencies.
At no time is the exchange in control of your funds. The decentralized exchanges are less convenient and more difficult to use for the average user than centralized exchanges are, but they often don't charge a brokerage fee. More importantly, decentralized exchanges have no access to your private keys. If a decentralized exchange gets hacked, there would be no immediate way for the hackers to steal your private keys, said Nishikawa.
But if your own machine gets hacked, your money is gone. As for trusting a cryptocurrency exchange, whether it's centralized or decentralized, Nishikawa said you need to do your homework first by researching the exchange's reputation and history. Unfortunately, once cryptocurrency is stolen, it's gone for good.
Remember, said Nishikawa, cryptocurrencies are digital and largely anonymous; therefore, the only things worth stealing are the private keys. Once those keys are stolen, the currency is almost always immediately spent.
Both consumers and businesses using and investing in cryptocurrency need to ensure that they can adequately protect and secure private keys and establish the integrity of any exchange involved in their transactions.
