The Bitcoin protocol is not just about sending money from A to B. It has many features and opens many possibilities that the community is still exploring. Here are some of the technologies currently being researched and in some cases, turned into real products and services. The most interesting uses of Bitcoin are probably still to be discovered.
Control against fraud
An unprecedented level of security is possible with Bitcoin. The network provides users with protection against most prevalent frauds like chargebacks or unwanted charges, and bitcoins are impossible to counterfeit. Users can backup or encrypt their wallet and hardware wallets could make it very difficult to steal or lose money in the future. Bitcoin is designed to allow its users to have complete control over their money.
All payments in the world can be fully interoperable. Bitcoin allows any bank, business or individual to securely send and receive payments anywhere at any time, with or without a bank account. Bitcoin is available in a large number of countries that still remain out of reach for most payment systems due to their own limitations. Bitcoin increases global access to commerce and it can help international trades to flourish.
With the use of cryptography, secure payments are possible without slow and costly middlemen. A Bitcoin transaction can be much cheaper than its alternatives and be completed in a short time. This means Bitcoin holds some potential to become a common way to transfer any currency in the future. Bitcoin could also play a role in reducing poverty in many countries by cutting high transaction fees on workers' salary.
Tips and donations
Bitcoin has been a particularly efficient solution for tips and donations in several cases. Sending a payment only requires one click and receiving donations can be as simple as displaying a QR code. Donations can be visible for the public, giving increased transparency for non-profit organizations. In cases of emergencies such as natural disasters, Bitcoin donations could contribute to a faster international response.
Bitcoin can be used to run Kickstarter-like crowdfunding campaigns, in which individuals pledge money to a project that is taken from them only if enough pledges are received to meet the target. Such assurance contracts are processed by the Bitcoin protocol, which prevents a transaction from taking place until all conditions have been met.

Imagine listening to Internet radio paid by the second, viewing web pages with a small tip for each ad not shown, or buying bandwidth from a WiFi hotspot by the kilobyte. Bitcoin is efficient enough to make all of these ideas possible.

Bitcoin can be used to develop innovative dispute mediation services using multiple signatures. Such services could make it possible for a third party to approve or reject a transaction in case of disagreement between the other parties without having control on their money. Since these services would be compatible with any user and merchant using Bitcoin, this would likely lead to free competition and higher quality standards.
Multiple signatures allow a transaction to be accepted by the network only if a certain number of a defined group of persons agree to sign the transaction. This could be used by a board of directors to prevent any member to spend parts of their treasury without other members' consent. This can also be used by banks to prevent theft by blocking payments above a threshold if the user does not provide additional credentials.
Trust and integrity
Bitcoin offers solutions to many of the trust problems that plague banks. With selective accounting transparency, digital contracts, and irreversible transactions, Bitcoin can be used as a ground to restore trust and agreement. Crooked banks cannot cheat the system to make a profit at the expense of other banks or the public. A future in which major banks would support Bitcoin could help to reinstate integrity and trust in financial institutions.
Resilience and decentralization
By its high decentralization, Bitcoin created a different form of payment network with an increased level of resilience and redundancy. Bitcoin can handle millions of dollars in trades without requiring military protection. With no central point of failure such as a data center, attacking the network is a more difficult project. Bitcoin could represent an interesting step forward in securing local and global financial systems.
All Bitcoin transactions are public and transparent and the identity of the people behind the payments is private by default. This allows individuals and organizations to work with flexible transparency rules. For instance, a business can choose to reveal certain transactions and balances only to certain employees just like a non-profit organization is free to allow the public to see how much they receive in daily and monthly donations.
Automated services usually have to deal with costs and limitations of cash or credit card payments. This includes all kinds of vending machines, from bus ticket booths to coffee machines. Bitcoin is suited to be used in a new generation of automated services as well as to cut their operating costs. Imagine self-driving taxis, or a store where your basket lets you pay your purchases without waiting at the queue. Many ideas are possible.
