The Bitcoin network and its technology demonstrate a high level of security. Cryptography and the Bitcoin protocol are characterized by transparency and confidentiality. All information from the bitcoin wallet, personal data, keys may be lost by users due to negligence; for this purpose, the Bitcoin system uses additional security practices today to protect participants from loss and theft.
Is hacking of the system acceptable?
The bitcoin system has been developed by professionals and has been working for several years now without complaints or user complaints about either cryptography or protocol. During the operation of the Bitcoin network, the security conditions have improved several times. The security score of the Bitcoin-network software depends on the rate at which software problems are detected and fixed. The more problems are discovered, the faster Bitcoin will work.
There have been deceptions and thefts of bitcoin users from exchangers and Bitcoin businesses; such circumstances have occurred, but they are in no way related to hacking the bitcoin network itself.
Bitcoin users are offered a toolkit of optimal security solutions and practices to preserve their funds and reduce the overall volume of losses and thefts. For example, there are offline bitcoin wallets, wallet encryption, transactions with mandatory multiple signatures, and special bitcoin devices for storing funds.
Is there regulation?
The protocol cannot be changed without the personal consent of each user of the network. It is the bitcoin users who determine which software is used. The reality is that it is impossible to grant any privileges to local authorities or jurisdictions—Bitcoin is globalized.
It is possible that a company may invest a large amount of money in mining equipment to control network computer power, which will help roll back past transactions or block them. There is no guarantee that in this way it is possible to achieve or gain a foothold in such a position; in this case it is necessary to invest as much as all the other miners of the world combined have invested.
Bitcoin can be used like any other global currency, and financial relations with currencies are regulated differently in each country. For example, in one country there are strict restrictions and rules, which means that the circulation of money becomes difficult. In those countries where Bitcoin is officially banned, government agencies simply impose restrictions on the development of their own domestic market and entrepreneurship, which simply diverts investment from this country.
The main disadvantages
1. Exchange-rate fluctuations
Even minor transactions by some companies can have an impact on the value of bitcoin. The exchange-rate fluctuations of Bitcoin funds will decrease with an increase in the market impact of the system. The new currency is news for the whole world; it's not so easy to predict or assume a Bitcoin development strategy.
2. Worldwide recognition
Many people still don't know about the existence of Bitcoin. The network is developing, but at the moment it has not yet received worldwide recognition.
3. Continuous optimization and development
Beta testing continues to accompany the bitcoin network. There are a number of unfinished functions that are being developed by specialists at this stage, as well as tools, services, and options that are not yet available. Developers are striving to upgrade Bitcoin to the most secure and accessible global system.
