A tale of buying and selling bitcoin


Now that you know where and how you can store bitcoin, it’s time to take a trip down the road cryptocurrency travels when you buy, sell, or trade it

Because bitcoin — and cryptocurrency in general — is somewhat of a nebulous concept, it may initially be unclear what happens to your real-world cash when topping up or offloading the coins in your BTC.com wallet. It’s easy to view this chain of events as an overly complex system, governed by higher powers that are not for the mere mortal to understand.

But that’s not true. While the price of bitcoin may be somewhat volatile, it also adheres to a logical, fairly simple set of guidelines. Bitcoin, after all, is a commodity — and it acts accordingly.

A simple example

Say, for example, you buy a sweater at a retail store. In exchange for ownership of said sweater, you offer a stated amount of currency (dollars, euros, rubles — whatever) to the sweater’s previous owner. Look back far enough, and you can follow ownership of that sweater all the way up the supply chain, up until its manufacture. If you wanted to get really meta, you could go back even further, tracing the materials sourced and used to create the sweater. The point is, when you are making a bitcoin purchase, just as when you buy a sweater, or a computer, or a car, you are not the first owner. All bitcoin that exists was first mined, then distributed among the blockchain through purchases and sales.

Exchanges: buy and sell

When buying bitcoin, it is common to do so from a bitcoin exchange. Our users in the United States can currently do this directly through their BTC.com wallet, thanks to our partnership with Kraken and its Kraken Direct brokerage service. Using real-world currency (usually via a credit or debit card), you will purchase a set amount of bitcoin. Obviously the amount of bitcoin you receive will vary, depending on the how much money you exchange, as well as the price of bitcoin. After making the purchase, the bitcoin is transferred to your wallet. Then you own the bitcoin.

Selling bitcoin can also be accomplished through an exchange. In this case, the transaction works oppositely of the way it did when you bought bitcoin. The exchange provides the funds, while you provide the bitcoin. In this way, exchanges essentially act as banks. Although with bitcoin you, the user, have much more control over your funds than you do with fiat currency.

Transaction fees

To be counted as official, a bitcoin transaction must be included on the blockchain. To be included on the blockchain in a timely manner, those transacting should pay a transaction fee to bitcoin miners. Miners prioritize transactions that pay them higher fees. If your transaction is prioritized, it will be recorded on the blockchain more quickly, which means you will have access to your funds sooner than if you opted to pay a lower fee.

The BTC.com wallet automatically uses a dynamic fee strategy to determine the optimal fee for your particular transaction. You can also always opt for the lowest possible fee. It’s also important to remember that transaction fees paid via a BTC.com wallet transaction are never paid to BTC.com itself, but rather the miners that will include the transaction on the blockchain.

Trading bitcoin

In addition to buying and selling, bitcoin can also be traded. In this case, exchanges will have a bit more control over your funds. We refrain from offering any sort of advice when it comes to trading and instead focus on the facts. Trading, however, is not without its risks, and should be approached with caution, knowledge, and experience (if not yours, then with the help of someone else’s).

When trading, bitcoin exchanges act as the middleman between buyer and seller. Each exchange operates what is known as an “order book.” Here, buyers are able to place orders for bitcoin purchases, stating how much bitcoin they would like and for what price. Sellers are able to see these orders, and either match that price or wait it out, in hopes that they will be able to offload their bitcoin for a potentially better deal.

Trading bitcoin is a bit like playing the stock market. Because currency values are constantly shifting, shrewd traders are able to ride the waves of currency (both real and digital), buying and selling at just the right time in order to maximize their profits. But beware—for every winner, there is also a loser.

Often, bitcoin traders’ funds sit with an exchange rather than in a wallet. This means they are not in control of their bitcoin until after they have withdrawn, received, and stored it safely in a bitcoin wallet. Trading bitcoin requires a lot of trust, so make sure that when you are ready to trade you are doing so with a reputable exchange. Money can be made trading, and it can be lost just as easily.
