Much of the trust in Bitcoin comes from the fact that it does not require trust. Bitcoin is a completely open source and decentralized. This means that anyone has access to the complete code at any time. Any R developer in the world can check how it works. All transactions and bitcoins created during their existence can be clearly consulted in real time by anyone.

In addition, Bitcoin is created to prevent a large number of financial crimes.What happens when bitcoins are lost? When a user loses his wallet, the effect is to remove the money from circulation.

Is Bitcoin legal?
As far as we know, bitcoin has not been made illegal by law in most territories. However, some territories (such as Argentina or Russia) severely restrict or prohibit foreign currencies. Other territories (such as Thailand) may limit licensing to certain entities such as Bitcoins bureaux de change.
Regulators from various territories are taking steps to provide individuals and businesses with rules on how to integrate this new technology into the regulated and conventional financial system.
Is Bitcoin useful for illegal activities?
Bitcoin is money and money has always been used for legal and illegal purposes. Cash, credit cards and banking systems far outnumber Bitcoin when it comes to financing the crime. Bitcoin can bring innovation to the payment systems and the benefits of such innovation are considered much more valuable than the potential drawbacks.
Bitcoin is designed to take a big step forward in monetary security and could also play a big role against many forms of financial crime. . Bitcoin transactions are irreversible and immune to fraudulent returns. Bitcoin allows you to secure money against theft using strong and useful mechanisms
Some concerns have arisen that Bitcoin may be more attractive to criminals because it can be used to make private and irreversible payments.

And Bitcoin and consumer protection?
Bitcoin is allowing people to make transactions under their own conditions. Each user can send and receive payments in a similar way to the current money but can make more complex agreements. Multiple signatures allow a transaction to be accepted by the network only if a certain number of people in a group agree to sign the transaction. This will enable innovative mediation services to be developed in the future. These services could enable a third party or individual to accept or deny a transaction if there is a disagreement between the two individuals without having control over the money. Unlike ordinary money and other methods of payment, Bitcoin always leaves a public proof that a transaction has been made, which can be used against fraudulent business.

Why do I have to wait 10 minutes?
The receipt of a payment is almost instantaneous with Bitcoin. However, there is a delay of 10 minutes on average before the network begins to confirm that transaction by including it in a block and before the received bitcoins can be spent. A confirmation means that there is a consensus on the network that the received bitcoins have not been sent to anyone else and are now owned by you. Once your transaction has been included in a block, it will be "buried" with more confirmations by the following blocks that are added to the chain, which will consolidate this consensus and decrease the risk of a revocation of the transaction.
What happens if I get a bitcoin when my computer is turned off?
Works correctly. Bitcoins will appear the next time you open your wallet. Bitcoins do not actually receive this software, but are added to a public accounting book shared with all devices on the network.

What is bitcoin mining?
Mining bitcoins is the process of investing computational capacity to process transactions, ensure network security, and get all participants synchronized. It could be described as Bitcoin's data center,

Is Bitcoin safe?
Bitcoin technology - protocol and cryptography - has a strong security record and the Bitcoin network is probably the largest distributed computing project in the world. The most common vulnerability is user failure.
Bitcoin was not previously hacked?
The rules of protocol and cryptography used for Bitcoin continue to work perfectly years after its creation, which is a guarantee that the concept is well designed. However, failures have been detected in security and have been solved over time by changes in the software. Like any other type of software, Bitcoin's security depends on the speed at which they are found and solve the problems. As these problems are discovered, Bitcoin will continue to mature
Could users conspire against Bitcoin?
It is not possible to change the Bitcoin protocol so easily. A Bitcoin client that does not comply with the rules, can not impose its own to the other users. In the current specification, it is not possible to incorporate double expense in the same block chain, nor to spend bitcoins without a valid signature. That is why it is not possible to generate uncontrolled quantities of bitcoins out of thin air, to spend foreign funds, to corrupt the network or something similar.
