A Quick Guide to Cryptocurrency Security



Everything You Need to Know About Security in Cryptocurrency

The popularity and rapid adoption of Bitcoin have led to a proliferation of other cryptocurrencies. Not all are created equal—the security of math backs some, and some are based on the centralized authority of an individual or organization. Many new currencies were made, resulting in scams. Here's an overview that can help you avoid these pitfalls.

What Is Cryptocurrency?

Cryptocurrency is a digital currency that uses encryption methods to control the creation of currency units and verify payment transfers. Bitcoin was the first decentralized cryptocurrency, but hundreds of others have been developed, including Ethereum, Ripple, and Litecoin. These cryptocurrencies are referred to as altcoins or alternative coins to distinguish them from Bitcoin.

Is Cryptocurrency Secure?

The decentralized nature of these currencies means no individual or organization can control them. However, each cryptocurrency uses public and private keys to send and receive funds to create an address. If you lose possession of your private key, someone else can control that digital currency. You can take many steps to protect yourself, but the most critical factor is keeping your key secure.

Cryptocurrency Security Tips

Here are some security tips to help you protect your cryptocurrency investments:

Understand Your Wallet

If you're planning to acquire Bitcoin or other altcoins, the first thing to do is understand the various cryptocurrency wallets. The safest place to store your private key is on a device you control, such as a dedicated hardware wallet or a hard drive on your computer. Online wallets can be convenient, but they're vulnerable to hackers and other threats.

Never Share Private Keys

Even if you're the only person accessing your key, never share it or post it online. The more access points to your crypto accounts that get out into the public, the greater the risk of theft is. As an added measure, use distinct passwords for each account and enable two-step verification when available

Back It Up

Cryptocurrency private keys are long strings of letters and numbers. If you're using a physical wallet, like a hard drive or a USB flash drive, protect your backups if the device is lost or damaged. Investors can similarly protect paper wallets with waterproof and fireproof safes.

Update Software

The biggest threat to cryptocurrency investments is hackers, who can exploit vulnerabilities in software to steal your funds. Be sure to keep all software on your computer up to date.

Use Two-Factor Authentication

Typically, your private key is encrypted and decrypted using a single password or passphrase. By requiring a unique code to be input each time you log in, two-factor authentication provides an additional degree of protection. This code can be sent by text message or generated by a smartphone app, like Authy or Google Authenticator.

Be Vigilant

Although your private key is virtually impossible to steal, you can lose your funds. If you notice any unusual activity in cryptocurrency wallets, look. New coins are often launched with little or no warning, and there have been several high-profile hacks of big exchanges in the past.

Beware of Phishing Scams

Phishing scams are an attempt to steal your private keys. A common scam involves linking a fake website that looks like an official exchange. The goal is to dupe you into entering your private key and send cryptocurrency directly to the hacker's wallet. You can't reverse the transaction even if you discover the theft after it happens. Phishing attacks probably won't be the last attempt to steal your cryptocurrency.


Be Wary of New Coins

A significant number of new altcoins are the product of Ponzi schemes, pump and dump schemes, or outright fraud. For this reason, some jurisdictions have taken action against cryptocurrencies or made it illegal to participate in initial coin offerings (ICOs). When evaluating an investment opportunity, use common sense and do your homework before participating in a crowd sale or pre-sale.

Be Selective About Exchanges

New coins are often traded at an exchange, so you should know the exchanges where the new currency will be available when you're considering an ICO. If an exchange is poorly designed or is poorly maintained by its owners, it may suffer from several vulnerabilities and open up avenues for hackers to access your information.

Don't Store All of Your Funds on a Single Platform

It might be tempting to withdraw all of your funds from an exchange and keep them in a wallet software or hardware wallet if you want to participate in speculative trading. However, you risk losing everything if the platform is hacked. Keeping some funds on an exchange gives you access to liquidity for larger trades and the flexibility to quickly get into and out of investments.


With cryptocurrencies growing in popularity worldwide, the need to ensure the security of your funds is essential. It's an exciting new technology, but it's not an asset for the faint of heart.

If you want to invest in cryptocurrencies, you should treat your wallet and private key as if they were a typical bank account. A little information and common sense may go a long way toward safeguarding your digital assets. Visit our blog now to learn more about cryptocurrencies.
