As far as we know, Bitcoin has not been classified as illegal currency by legislative bodies in most jurisdictions. However, some jurisdictions, such as Argentina and Russia, severely restrict or ban foreign currencies. Other jurisdictions (e.g. Thailand) may restrict the issuance of licenses to certain entities, e.g.

Regulators from different jurisdictions are taking steps to provide individuals and businesses with some rules on how to integrate this new technology with the formal, regulated financial system. For example, the U.S. Treasury Department’s Financial Crimes Enforcement Network (FinCEN) has issued non-binding guidance on how to describe certain activities involving virtual currencies.

## Can Bitcoin be regulated?

The Bitcoin protocol itself cannot be modified unless nearly all users collaborate to choose which software to use. It would be unrealistic to attempt to give a regional governing body special powers within the rules of the global Bitcoin network. Any wealthy organization can choose to invest in mining hardware to control half of the computing power in the entire network, thereby enabling the freezing and reversal of recent transactions. However, there is no guarantee that they will always have this capability, as the investment would need to be equal to that of all other miners around the world combined.

However, it is possible to regulate the use of Bitcoin in a manner similar to regulating any other currency. Like the U.S. dollar, Bitcoin can be used for a variety of purposes, some of which may be considered legal or not compliant with the laws of every jurisdiction. At this point, Bitcoin is like any other tool or resource, subject to regulations that vary from country to country.

It would also be difficult to use Bitcoin under restrictive regulations, making it difficult to determine what percentage of users would continue to use the technology. Governments that choose to ban Bitcoin will hinder the development of domestic businesses and markets, diverting innovation to other countries. As always, the challenge for regulators is to develop effective solutions without harming the development of emerging markets and businesses.

Bitcoin technology, including the protocol and cryptography, has a strong security record, and the Bitcoin network is perhaps the largest distributed computing project in the world. The most common vulnerability in Bitcoin is user error. Bitcoin wallet files that store private keys can be accidentally deleted, lost, or stolen. This is very similar to physical cash stored electronically. Fortunately, users can protect their funds with solid security strategies and providers that offer good security levels and theft or loss insurance.

## What are the disadvantages of Bitcoin?

Volatility-
The total value of Bitcoin in circulation and the number of businesses using Bitcoin are still very small compared to their possible size. Therefore, relatively small events, transactions or business activities can significantly affect its price. In theory, this volatility will decrease as Bitcoin's market and technology mature. The world has never seen an emerging currency before, so it’s really hard to imagine how it will progress.
(Also exciting).

In development stage -
Bitcoin software is still in beta version, and many unfinished features are in the active development stage. New tools, features and services are being developed to make Bitcoin more secure and accessible to the wider public. Some of these features are not currently available to every user. Most Bitcoin businesses are new and do not yet offer insurance. Generally speaking, Bitcoin is still in the process of maturing.

Related content is introduced in detail. From a user's perspective, Bitcoin is a mobile application or computer program that provides a personal Bitcoin wallet that users can use to pay and receive Bitcoins. This is how Bitcoin works for most users. Behind the scenes, the entire Bitcoin network shares a public ledger called the "blockchain." This ledger contains every transaction processed, allowing the user's computer to verify the validity of each transaction. The authenticity of each transaction is protected by an electronic signature corresponding to the sending address, which gives users full control over the Bitcoins transferred from their own Bitcoin address. Additionally, anyone can leverage the computing power of specialized hardware to process transactions and be rewarded with Bitcoins for doing so. This service is often referred to as "mining".
