By taking three small precautionary steps, you can help keep yourself safe from mishandling and losing all your tokens, as well as assembling a line of defence from hackers all over the world.
1. Minimize the opportunity for human error
Tip #1: When sending and receiving crypto, always copy and paste the address rather than typing it out manually. There’s nothing worse than blasting off your tokens into the abyss just because you thought the number “0” was an uppercase “O”. Be sure to reread and confirm to guarantee the accuracy.
Tip #2: NEVER share your private key with other parties. Once it’s out there, your wallet is instantly exposed to risk.
Tip #3: Don’t send your coins to the wrong crypto choice on exchanges. A minor slipup such as sending your Bitcoin to an Ethereum address could result in lost Bitcoin. Be sure to always double check.
2. Minimize the threat of external stupidity
Tip #4: Be wary of using wallets that store your private keys for you. At the end of the day, whoever holds your private key has power over your tokens.
Tip #5: You should also seek to spread your holdings over multiple platforms to diversify some of the risk. For example, if you plan to trade with about $2,000 worth of tokens, there is no need to keep your entire $20,000 worth of holdings on an exchange wallet. You can eliminate some of the risk by keeping the majority of your holdings in one (or a few) hardware wallets. That way if a certain exchange wallet gets hacked, you’re only out $2,000 and not the remaining $18,000.
Tip #6: If you’re participating in an ICO, you need to use a wallet such as MyEtherWallet that you’re in complete control of. When ICOs release their tokens they will often be sent back to the address you used to send your investment. If you sent the Ethereum from an exchange, they most likely will not credit you those tokens.
3. Eliminate the threat of malicious players
Tip #7: If you’re not very careful, you could end up falling prey to an exchange phishing scam. What these scams do is send you content or urgent messages that take you to a nearly identical exchange site to lure you to sign up using your sensitive login information. Additionally, these sites could infect your computer with malware and that’s a whole new nightmare. Be sure to bookmark your exchange site, or type it in directly every time. Always confirm you’re clicking on the right one.
Tip #8: When signing up for an exchange or wallet, always use the security options available. Always use two-factor authentication (2FA), Google authenticator instead of SMS, strong passwords, and secure email accounts.
Tip #9: As a good rule of thumb, your large quantities of tokens should be stored on a hardware wallet. These hardware wallets are NOT connected to the Internet, and your tokens are 100 percent safe as long as they are not online. Most software wallets do a great job of keeping your coins secure, but the fact that they are still online (some even hold onto your private keys) is an inherent risk.
Tip #10: Always double check your addresses when sending tokens. There is a type of malware called CryptoShuffler that waits for an infected user to paste the recipient address, only to swap out the original address for one belonging to the hacker’s wallet.
