Some things you need to know
If you're getting started with Bitcoin, there are a few things you should know. Bitcoin lets you exchange money and transact in a different way than you normally do. As such, you should take time to inform yourself before using Bitcoin for any serious transaction. Bitcoin should be treated with the same care as your regular wallet, or even more in some cases!
Securing your wallet
Like in real life, your wallet must be secured. Bitcoin makes it possible to transfer value anywhere in a very easy way and it allows you to be in control of your money. Such great features also come with great security concerns. At the same time, Bitcoin can provide very high levels of security if used correctly. Always remember that it is your responsibility to adopt good practices in order to protect your money.
Bitcoin price is volatile
The price of a bitcoin can unpredictably increase or decrease over a short period of time due to its young economy, novel nature, and sometimes illiquid markets. Consequently, keeping your savings with Bitcoin is not recommended at this point. Bitcoin should be seen like a high risk asset, and you should never store money that you cannot afford to lose with Bitcoin. If you receive payments with Bitcoin, many service providers can convert them to your local currency.
Bitcoin payments are irreversible
A Bitcoin transaction cannot be reversed, it can only be refunded by the person receiving the funds. This means you should take care to do business with people and organizations you know and trust, or who have an established reputation. For their part, businesses need to keep track of the payment requests they are displaying to their customers. Bitcoin can detect typos and usually won't let you send money to an invalid address by mistake, but it's best to have controls in place for additional safety and redundancy. Additional services might exist in the future to provide more choice and protection for both businesses and consumers.
Bitcoin is not anonymous
Some effort is required to protect your privacy with Bitcoin. All Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address. However, the identity of the user behind an address remains unknown until information is revealed during a purchase or in other circumstances. This is one reason why Bitcoin addresses should only be used once. Always remember that it is your responsibility to adopt good practices in order to protect your privacy.
Unconfirmed transactions aren't secure
Transactions don't start out as irreversible. Instead, they get a confirmation score that indicates how hard it is to reverse them (see table). Each confirmation takes between a few seconds and 90 minutes, with 10 minutes being the average. If the transaction pays too low a fee or is otherwise atypical, getting the first confirmation can take much longer.
Bitcoin is still experimental
Bitcoin is an experimental new currency that is in active development. Each improvement makes Bitcoin more appealing but also reveals new challenges as Bitcoin adoption grows. During these growing pains you might encounter increased fees, slower confirmations, or even more severe issues. Be prepared for problems and consult a technical expert before making any major investments, but keep in mind that nobody can predict Bitcoin's future.
Government taxes and regulations
Bitcoin is not an official currency. That said, most jurisdictions still require you to pay income, sales, payroll, and capital gains taxes on anything that has value, including bitcoins. It is your responsibility to ensure that you adhere to tax and other legal or regulatory mandates issued by your government and/or local municipalities.

The digital wallet can be hardware-based or web-based. The wallet can also reside on a mobile device, on a computer desktop, or kept safe by printing the private keys and addresses used for access on paper. But how safe are any of these digital wallets? The answer to this depends on how the user manages the wallet. Every wallet contains a set of private keys without which the bitcoin owner cannot access the currency. The biggest danger in bitcoin security is the individual user perhaps losing the private key or having the private key stolen. Without the private key, the user will never see her bitcoins again. Besides losing the private key, a user can also lose her bitcoin by computer malfunctions (crashing a hard drive), by hacking, or by physically losing a computer where the digital wallet resides.bitcoin кошелек Its block time is 13 seconds, compared to 10 minutes for bitcoin.bitcoin цены bitcoin шрифт bitcoin руб лотереи bitcoin bitcoin block bitcoin all bitcoin рост bitcoin de polkadot bitcoin exchanges
