A private key can allow anyone to authorize transactions on the blockchain. This is why security and privacy are key issues for investors of Bitcoin. Since the public address is visible to anyone, criminals tend to try and steal large holdings.

The advantage is that you can create numerous public addresses. This allows you to spread your holdings and cheat the system. You can keep important investments in public addresses that are not connected to those with transactions.

All transactions are recorded publicly on the blockchain. The history of these transactions is available for anyone to view. Only your public key appears with the transaction, keeping identifying user information private. This allows for transactions to be confidential, but not anonymous.

Transactions in Bitcoin (₿) are verified by network nodes. This is done through cryptography. It is then recorded in a ledger that is distributed publicly. This ledger is known as a blockchain. As a decentralized digital currency, Bitcoin operates without the need of intermediaries. The currency can be transferred between users without a single administrator or central bank.

Step One: Choose a Crypto Trading Service or Venue

Choosing a crypto trading venue or service is the first step to buying Bitcoin. Some of the trading services and venues where you can buy Bitcoin are:

• cryptocurrency exchanges: This option is convenient since it offers a variety of features. You also get more cryptocurrencies to trade with.
• payment services
• brokerages

When you sign up for a cryptocurrency exchange, you can buy, sell, and hold cryptocurrency. You should go for an exchange that allows you to withdraw crypto to your own personal online wallet for safekeeping.

Cryptocurrency Exchanges

There are many types of cryptocurrency exchanges. The ethos of Bitcoin emphasizes individual sovereignty and decentralization. There are exchanges that allow anonymity to its users. They do not require users to enter personal information when they sign up. These exchanges are usually decentralized and operate autonomously. This means they are not controlled from a central point.

A lot of such systems can be used for despicable activities. A positive way they are used is by providing services to the world's unbanked population. For refugees and those living in countries with little to no infrastructure for government credit or banking. Having anonymous exchanges helps to bring them into the mainstream economy.

Unfortunately, a lot of the popular exchanges are not decentralized. They follow laws that require users to submit proof of identity. They offer a lot of features and set their own criteria on which tokens to trade. Some of the exchanges in the United States include:

• Coinbase
• Kraken
• Gemini
• FTX.US
• Binance.US

It is important to use safe internet practices. Ensure you have two-factor authentication and a uniquely long password.

Step Two: Connect Your Exchange to a Payment Option

Depending on the exchange, the personal documents needed may include;

• pictures of a driver's license
• pictures of your Social Security number
• information about your employer
• Information on your source of funds

After your identity is verified, the next step is to get a payment option. You can buy cryptocurrency using a credit card. However, it is not advised since cryptocurrency has price volatility. There is a chance it could inflate the overall cost of buying a coin. You should ensure your bank allows deposits at the exchange you pick.

You will incur different fees when depositing using a bank account, debit, or credit card. Coinbase is a reasonable exchange for beginners to start with. It has a 3.99% fee for debit and credit cards and a 1.49% fee for bank accounts. You should look into the fees associated with each payment option before choosing one.

Each transaction is charged differently. Some exchanges offer a flat rate or a percentage of the trading amount. When you use a credit card, there is a processing fee added to the transaction fee.

Step Three: Place an Order

Recently, cryptocurrency exchanges have grown significantly in terms of liquidity and the features offered. This is because of the change in perception of cryptocurrencies. Previously, the industry was perceived to be a scam. This view has changed so much that it has attracted some big players in the financial services industry.

In addition to having a variety of order types, exchanges also offer ways to set up recurring investments. This allows clients to average their dollar-cost into investments of their choice. When you use Coinbase, you can set recurring daily, weekly or monthly purchases.

Step Four: Safe Storage

You can securely store your digital assets in Bitcoin and cryptocurrency wallets. When you have your crypto outside of the exchange, it is placed in your personal wallet. This gives you control over the private key to your funds. You can also store funds away from an exchange. This allows you to avoid the risk of hacking and losing your funds.

A lot of exchanges offer wallets but do not focus on security. You should not use an exchange wallet for large storage. You should also not keep your cryptocurrency in the exchange wallets for a long time.

There are wallets with more features than others. Some can only store Bitcoin, while some offer the ability to hold many different types of altcoins. There is the option of swapping one token for another in some wallets. When you are choosing and financing a Bitcoin wallet, you should consider all your options.
