Question 5

Recommendations for storing cryptocurrencies

Accepted Answer

Follow these guidelines to reduce the chance of losing funds to hackers or malware.

Remember that the most vulnerable place in the cryptocurrency system is you - the user. Hackers and scammers skillfully use their communication skills to gain your trust.

Learn how cryptocurrencies work, what private keys are and how to store them. Never make transactions in a hurry - always check what and where you enter: amounts and addresses. Do not share your private keys, passwords and other important information with anyone.

Use separate email addresses for registering on cryptocurrency exchanges and other services, as well as unique passwords for each of them. Yes, it can be inconvenient, but convenience and security are two different things: the more convenience, the less security, keep that in mind.

When creating a new wallet for cryptocurrencies on your devices, write down the password to it, as well as the seed phrase (seed) - it is in fact your money, because only by seed you can restore access to your wallet in case of loss of a device with a wallet or failure systems.

Keep the seed and password from the wallet on another device in encrypted form or on paper, but in such a way as to ensure 100% safety of the medium and restrict access to them by other persons. Alternatively, it can be a flash drive that you save in a safe place so that no one can take it and overwrite the data on it.

Only you are responsible for the safety of your funds.

Question 6

It is safe

Accepted Answer

Bitcoin is a secure technology based on data encryption and anonymity. Bitcoin coins are stored in a wallet file on your personal computer. You need to protect it from access by third parties in the same way as a real wallet.

The "BitCoin" project is 5 years old, and not a single information security specialist has tried to hack it.

From a technological point of view, the distributed system "BitCoin" has gone far ahead of traditional banking processing centers. The principle of operation of Bitcoin is more like working with "cash" than working with a payment card.

Question 7

What are bitcoin transactions?

Accepted Answer

Each transaction contains the number of tokens to be transferred, the sender&#x27;s input address, the recipient&#x27;s output address, and a private key (known only to the sender and used in conjunction with the public key to create an unforgeable message signature). The user who owns the private key of his account enters only the sender&#x27;s address, after which the transaction is confirmed by the miners. The security and reliability of this process is ensured by cryptographic algorithms. It must be understood that the blockchain is a chain consisting of all transactions since the creation of the network.
