Left without a use case, Bitcoin largely exists in two locations: centralized exchanges and believers' cold storage wallets. These locations are.

While it was designed as a way of conducting digital, peer-to-peer transactions, the technology is not scalable at this point. The benefit of using this methodology is that users on the Bitcoin network do not need to know or trust each other, nor do they rely on a third party as the central authority that has the final say on a transaction.

The Bitcoin network can only handle 7 transactions per second. If you want to read more on the specifics of the proof-of-work transaction speed issue, check out my previous article below:. The problem, though, is that the batch is only large enough to fit so many transactions. On the other hand, if there is a long list of transactions ahead of you, your coffee transaction might not make it into that next batch. What ends up happening is that your transaction gets queued up for the next batch.
The queue that the transaction is waiting in is called the mempool. So now you have to wait another 10 minutes after the previous batch of transactions is completed; i. Even then, there is no guarantee. Hopefully, by now, you get the point and can see how burdening it will become to buy even a cup of coffee with Bitcoin.
On centralized exchanges, all of the bitcoin is stored in a single location. Your Bitcoin and mine are together. The exchange simply manages a database that adds and subtracts a record of the Bitcoin you own, based on each trade. The exchange may disappear one day with all of your coins, or just flat-out refuse to give you the coins you purchased.
In the current state of Bitcoin, I believe that the only substantial use case that it has is a store of value, similar to gold. It is a speculative asset because it has no practical value outside of the fact that there is a promise of future value. The majority of people who have Bitcoin hold it for that promise, while a few may transact short-term to hedge against that bet.
As a store of value, Bitcoin has several favorable properties. First of all, it can be owned and easily stored. Unlike gold, Bitcoin can be stored on a USB stick, regardless of the amount you own. Gold takes up physical space, and holding large amounts of it can become noticeable. Bitcoin also has a fixed amount. In total, there will be no more than 21 million Bitcoin available to the world. Gold, while rare, continues to be mined, and the supply continues to increase. Bitcoin is also hard to imitate. It cannot be counterfeited, although scammers can sell to ignorant buyers.
An educated buyer, on the other hand, can much more easily spot fake Bitcoin than fake Gold or counterfeit cash — they can just check the blockchain, which holds a public record of every Bitcoin in circulation. Finally, Bitcoin is becoming more widely understood — people are curious.
Bitcoin Has Lost Steam. But Criminals Still Love It.
As the Bitcoin community continues to develop more technology to layer on top of the Bitcoin blockchain, the use cases for the digital currency may increase in the future. For now, it remains a speculative and unscalable asset that is currently held as a store of value.

Comparing Ripple vs. Bitcoin
Get started. Open in app. Specifically, cryptographic digital signatures enable a user to sign a digital asset or transaction proving the ownership of that asset. With the appropriate architecture, digital signatures also can be used to address the double-spend issue.
When cryptography started becoming more broadly available and understood in the late s, many researchers began trying to use cryptography to build digital currencies. These early digital currency projects issued digital money, usually backed by a national currency or precious metal such as gold. Although these earlier digital currencies worked, they were centralized and, as a result, they were easy to attack by governments and hackers. Early digital currencies used a central clearinghouse to settle all transactions at regular intervals, just like a traditional banking system.
Unfortunately, in most cases these nascent digital currencies were targeted by worried governments and eventually litigated out of existence. Some failed in spectacular crashes when the parent company liquidated abruptly. To be robust against intervention by antagonists, whether legitimate governments or criminal elements, a decentralized digital currency was needed to avoid a single point of attack.
Bitcoin is such a system, completely decentralized by design, and free of any central authority or point of control that can be attacked or corrupted. Bitcoin represents the culmination of decades of research in cryptography and distributed systems and includes four key innovations brought together in a unique and powerful combination. Bitcoin consists of:. Nakamoto combined several prior inventions such as b-money and HashCash to create a completely decentralized electronic cash system that does not rely on a central authority for currency issuance or settlement and validation of transactions.
This elegantly solves the issue of double-spend where a single currency unit can be spent twice. Previously, the double-spend problem was a weakness of digital currency and was addressed by clearing all transactions through a central clearinghouse. The bitcoin network started in , based on a reference implementation published by Nakamoto and since revised by many other programmers.

The largest transaction processed so far by the network was million US dollars, transmitted instantly and processed without any fees. Satoshi Nakamoto withdrew from the public in April of , leaving the responsibility of developing the code and network to a thriving group of volunteers. The identity of the person or people behind bitcoin is still unknown. However, neither Satoshi Nakamoto nor anyone else exerts control over the bitcoin system, which operates based on fully transparent mathematical principles.
The invention itself is groundbreaking and has already spawned new science in the fields of distributed computing, economics, and econometrics. It can be used to achieve consensus on decentralized networks to prove the fairness of elections, lotteries, asset registries, digital notarization, and more.
Bitcoin is a technology, but it expresses money that is fundamentally a language for exchanging value between people.
We will reuse these stories throughout the book to illustrate the real-life uses of digital money and how they are made possible by the various technologies that are part of bitcoin. Each of these stories is based on real people and real industries that are currently using bitcoin to create new markets, new industries, and innovative solutions to global economic issues. To join the bitcoin network and start using the currency, all a user has to do is download an application or use a web application.
Because bitcoin is a standard, there are many implementations of the bitcoin client software. There is also a reference implementation, also known as the Satoshi client, which is managed as an open source project by a team of developers and is derived from the original implementation written by Satoshi Nakamoto.
Mobile clients for smartphones, such as those based on the Android system, can either operate as full clients, lightweight clients, or web clients. Some mobile clients are synchronized with a web or desktop client, providing a multiplatform wallet across multiple devices but with a common source of funds. The choice of bitcoin client depends on how much control the user wants over funds.
A full client will offer the highest level of control and independence for the user, but in turn puts the burden of backups and security on the user. On the other end of the range of choices, a web client is the easiest to set up and use, but the trade-off with a web client is that counterparty risk is introduced because security and control is shared with the user and the owner of the web service.
If a web-wallet service is compromised, as many have been, the users can lose all their funds.
