Bitcoin is the first and likely the most well-known example of a cryptocurrency—virtual money you can use to buy and sell goods and trade for cash. It launched in 2009, but Bitcoin didn’t become a household name until around 2017. That’s when it made headlines around the world as the price per bitcoin tripled in just a few weeks to nearly Kshs2,000,000. Interest in the cryptocurrency generally waned as prices fell to under 350,000 within a year, but Bitcoin eventually came roaring back, and the underlying blockchain technology that allows it to work hasn’t disappeared.
How Does Bitcoin Work?
Bitcoin is a decentralized and completely digital currency. Unlike fiat currencies, such as the Kenya Shilling, U.S. dollar, euro or British pound, governments don’t create or back bitcoins.
Bitcoin and other cryptocurrencies—there are many—are powered by “blockchain” technology. The Bitcoin blockchain is a decentralized public ledger, which might sound like technobabble, but isn’t difficult to understand as a concept.
The Bitcoin blockchain is a public ledger (or database) that’s created and managed by a large network of computers rather than a single entity or central bank—that’s what makes it decentralized.
New information, such as recent transactions, are grouped together to form a block. The block is then added (or chained) to the existing database. Once new information is added, it can’t be edited or deleted, and anyone can review the Bitcoin blockchain database. The result is a permanent record of Bitcoin transactions that’s available for public review.
For example, if you send bitcoins to someone else, an uneditable record of the transaction is added to the ledger, which is synced on tens of thousands of computers around the world.
Bitcoin also allows for transactions that remain anonymous to a certain extent. While there’s a public record of the transaction from person A to person B, there isn’t any identifying information about who person A and B are. However, anonymity goes out the window if you publish your Bitcoin address (the address you use to receive the currency) publicly. With your Bitcoin address, someone can see your transactions and even view the balance associated with it.
All of this complex math requires a lot of computational power, which is where Bitcoin miners come in. Miners allow use of their computers to process transactions and, in return, they receive bitcoins as payment. Anyone can set their computer up to mine Bitcoin, although the cost of electricity to power your computer may be more than you earn in the currency.
Should I Buy Bitcoin?
In addition to earning bitcoin from mining, you can buy and sell it online. But before you do, consider why you want to own it and the risk involved.
You can use Bitcoin to send a payment to someone else, and some companies accept it as a form of payment. However, Bitcoin’s volatile price doesn’t make it an ideal currency for day-to-day transactions. After all, you don’t want to spend KES100,000 worth of bitcoin on a new computer to find out the same amount of bitcoin is worth KES300,000 a few weeks later.
Instead, many people view the cryptocurrency as a store of value, similar to gold. While you can’t pay for most purchases with gold, you may want to buy gold because you think it will be worth more later.
People have made money buying Bitcoin as an investment. However, as with other investments, there are risks, and people have also lost lots of money selling their bitcoins for less than they bought them for. Others lost their entire investment when the platform they used to purchase their bitcoin was hacked, and unfortunately there was no way to track down the hackers or get their investment back. Keep the high level of risk in mind as you consider whether to buy.
How to Buy Bitcoin
You can buy bitcoin on these platforms using different methods, such as a credit card, bank account or by trading other cryptocurrencies. There will likely be a fee for each transaction, and the price of bitcoin may vary slightly from one platform to another.
You’ll also need a digital wallet when you buy bitcoin. Your bitcoins aren’t technically stored in your wallet—they’re part of the public Bitcoin blockchain. However, your digital wallet is where you keep your public and private key.
The public key can be shared with others and lets them send you bitcoin. Your private key should never be shared with anyone, because that’s what lets you send bitcoin to others. It’s a bit like a password to your online bank account. Other people can send you money if you give them your bank account number, but you’re the only one who can log into your bank account to access the funds.
Many public platforms let you purchase, sell and transfer bitcoin, and create a digital wallet for you on the platform. Platforms generally simplify the process, and allow you to manage your cryptocurrency accounts with a user-friendly interface like you would many other online accounts. The safest way to store bitcoin, however, is to keep your private key hidden somewhere, such as a thumb drive or written down on a piece of paper.
What Is the Future of Bitcoin?
The blockchain technology that’s the backbone of the Bitcoin network has many practical uses and may be adopted by different businesses in the future. Cryptocurrencies, in general, may also become more popular in the future. However, it’s impossible to say if Bitcoin will remain the most popular cryptocurrency or if something else will take its place.
Will Buying Bitcoin Impact Your Credit?
The money you keep in checking, savings or investment accounts doesn’t impact your credit history or scores. Your income and overall net worth also doesn’t factor into your credit. As a result, purchasing bitcoin won’t affect your credit. However, if you buy a lot of bitcoin hoping to make a quick buck and then its value drops, you might find yourself unable to pay other bills—and missing those payments could hurt your credit. You might also run into credit trouble if purchasing bitcoin causes you to run up a high credit card balance that increases your credit utilization, and results in missed payments if you can’t afford to pay it off.
