is one way of incentivizing users to help maintain an accurate historical record of who owns what on a blockchain network. Bitcoin uses proof of work, which makes this method an important part of the crypto conversation. Blockchains rely on users to collate and submit blocks of recent transactions for inclusion in the ledger, and Bitcoin’s protocol rewards them for doing so successfully. This process is known as mining.

Each cryptocurrency works slightly differently, but they all use something called blockchain technology. Imagine a huge online notebook where every transaction is recorded. This notebook is called a blockchain. Once a transaction is added, it can’t be changed, and everyone can see it. This transparency and security are what make cryptocurrencies trustworthy and attractive to many people.

Once you’ve decided on an exchange and a cryptocurrency, it’s time to secure your investment. You’ll need a cryptocurrency wallet to store your digital coins safely. Wallets can be online (hot) or offline (cold).

Cryptocurrency is a relatively risky investment, no matter which way you slice it. Generally speaking, high-risk investments should make up a small part of your overall portfolio — one common guideline is no more than 10%. You may want to look first to shore up your retirement savings, pay off debt or invest in less-volatile funds made up of stocks and bonds.

The first step to securing your crypto is setting up strong, unique passwords for your accounts on exchanges and wallets. Weak passwords make it easier for hackers to gain access. Additionally, always enable two-factor authentication (2FA) for an extra layer of protection. This means even if someone gets hold of your password, they’ll still need a second code to log in.

Cryptocurrencies use cryptography to encrypt sensitive information, including the private keys – long alphanumeric strings of characters – of crypto holders. Think of private keys as the passwords that determine the ownership of cryptocurrencies. Keep in mind that cryptocurrencies cannot be stored outside of the blockchain. They are permanently based on the blockchain. Hence, when someone says they own X amount of coins, what they really mean is that their password can legitimately claim X amount of coins on the blockchain.

These private keys are what crypto holders store on their wallets, which, as you must have guessed, are special kinds of software or devices designed specifically for this purpose. In instances where a crypto holder loses access to his or her private key, the cryptocurrencies associated with such keys could be lost permanently.

For many cryptocurrencies, another important element is the total number of coins that can ever exist is often fixed. For instance, there will be only 21 million bitcoins created, of which more than 18 million are already in circulation. This deflationary-based system is the complete opposite of what we have in traditional finance, where governments have the license to print an infinite number of fiat notes and inadvertently devalue their currencies.

The world would have to wait until 2009, before the first fully decentralized digital cash system was created. Its creator had seen the failure of the cypherpunks and thought that they could do better. Their name was Satoshi Nakamoto, and their creation was called Bitcoin.

Whoever has the private key owns the cryptocurrency, so don’t lose your wallets! Cryptocurrency is pseudonymous, remember? There is no way to prove your own cryptocurrency unless you have the keys to it.
