What is a Crypto Wallet?

A crypto wallet is a program created to store, send and receive digital currencies, monitor balances, and connect different blockchains with public and private keys. There are tons of cryptocurrency wallets, which are either hot or cold. Crypto wallets hold an individual’s private key, which is their identity, to the digital currencies market; thus, anyone who gets hold of it can conduct fraudulent transactions.

Use Cold Wallets

Unlike hot wallets, cold storage wallets don’t rely on an internet connection. They save coins offline and hence solve security breaches, a common problem with hot wallets. Cold wallets have two alternatives; paper and hardware wallets.

Hardware Wallets

A hardware wallet is a tool that does not rely on the internet and only connects to the internet when users need it to receive or send payments and disconnects after executing transactions. A hardware wallet is better than paper wallets due to some improved storage solutions. Trezor One and the Nano Ledger X are examples of hardware wallets. These wallets confirm transactions using private keys stored offline. Using a backup seed key, a user can retrieve their funds if the device is lost or broken.

Paper Wallets

As the name suggests, the wallet is made of paper. Paper wallets were primarily popular in the early years of bitcoin as a system of putting digital currencies as physical records by printing a person’s keys on a paper. The record comprises all the data required to produce cryptocurrency private keys and construct a wallet of keys. 

However, there is no way to retrieve private keys once lost, and if the paper wallet gets damaged, say, in a house fire, a user will lose their money. Therefore paper wallets are best used to store long-term money.

Diversified Portfolio

A digital currency portfolio lets users manage all cryptocurrencies they hold in a single place. Information on the crypto coins a user has and their amount value is visible, and also, one can learn to keep track of their crypto coins in real-time. Before purchasing cryptocurrency, one can determine whether it would add value to the portfolio.

It’s recommended to use cryptocurrencies for a broadly diversified asset class of 3-7 cryptocurrencies. Diversifying across multiple asset classes allows you to decrease exposure risks and improve risk-adjusted return.

Beware of Clipboard Hacking

Transfer of cryptocurrency involves long and hard to remember wallet addresses. Hackers are aware that the average person would typically copy these addresses from one platform and paste them to another.

Therefore, they have come up with ingenious methods to monitor clipboards for crypto addresses. Many users fall prey and carry out transactions to hackers’ wallets, leaving them with little recourse. It’s essential to be cautious and cross-check copied and pasted addresses before conducting any transaction.

This kind of malware runs in the computer background, unidentified. Therefore, anti-malware experts suggest that it’s vital to have the latest anti-virus software installed and firewall and make double-checking addresses of the safety protocols.

Don’t get phished

Phishing scams via deceptive advertisements and emails are rampant in the world of cryptocurrency. Be cautious when making crypto transfers and avoid any questionable and unknown links.

In the latest cryptocurrency heist, a hacker community called “CryptoCore” attacked virtual currency exchanges by spear-phishing campaigns. Attackers robbed bitcoin worth $200 million over two years, attacking businesses in the U.S. and Japan since 2018. ClearSky reported that CryptoCore had initiated a surveillance process to locate the cryptocurrency exchange employees and security officers’ email addresses before a spear-phishing attack. The hacker community attacked by using fake domains that impersonate affiliated organizations and staff and embed malicious links in documents via email.

Use Secure Internet

Use a secure internet connection and avoid public Wi-Fi networks when trading or engaging in crypto transactions. Use a VPN for increased protection and when accessing your home network. A VPN updates your IP address and location to shield your browsing activities from malicious attacks.

Change Your Password Regularly

Research has revealed that three-quarters of millennials in the U.S use the same password on over ten devices, applications, and other social media pages. It also claimed that most of them used the same password at more than 50 locations. Make sure you have a strong and complicated password that is almost impossible to unlock and change it frequently. If you have several wallets, use different keys. For additional protection, opt for two-factor or multi-factor authentication.

Maintain Multiple Wallets

Since wallet creation is limitless, you can diversify your crypto investment portfolio by holding various wallets. You can use one wallet for your regular purchases and store the rest of the money in a different wallet. Having multiple wallets safeguards your portfolio and reduces the losses of crypto account breaches.
