Bitcoin is a new currency that was created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are made with no middle men – meaning, no banks! Bitcoin can be used to book hotels on Expedia, shop for furniture on Overstock and buy Xbox games. But much of the hype is about getting rich by trading it. The price of bitcoin skyrocketed into the thousands in 2017.

Why bitcoin?
Bitcoins can be used to buy merchandise anonymously. In addition, international payments are easy and cheap because bitcoins are not tied to any country or subject to regulation. Small businesses may like them because there are no credit card fees. Some people just buy bitcoins as an investment, hoping that they’ll go up in value.

Buying bitcoins
Buy on an Exchange
Many marketplaces called “bitcoin exchanges” allow people to buy or sell bitcoins using different currencies. Coinbase is a leading exchange, along with Bitstamp and Bitfinex. But security can be a concern: bitcoins worth tens of millions of dollars were stolen from Bitfinex when it was hacked in 2016.

Transfers
People can send bitcoins to each other using mobile apps or their computers. It’s similar to sending cash digitally.
Mining
People compete to “mine” bitcoins using computers to solve complex math puzzles. This is how bitcoins are created. Currently, a winner is rewarded with 12.5 bitcoins roughly every 10 minutes.

Bitcoin wallet
Bitcoins are stored in a “digital wallet,” which exists either in the cloud or on a user’s computer. The wallet is a kind of virtual bank account that allows users to send or receive bitcoins, pay for goods or save their money. Unlike bank accounts, bitcoin wallets are not insured by the FDIC.

Wallet in cloud: Servers have been hacked. Companies have fled with clients’ bitcoins.
Wallet on computer: You can accidentally delete them. Viruses could destroy them.
The anonymity of bitcoin
anonymous bitcoin
Though each bitcoin transaction is recorded in a public log, names of buyers and sellers are never revealed – only their wallet IDs. While that keeps bitcoin users’ transactions private, it also lets them buy or sell anything without easily tracing it back to them. That’s why it has become the currency of choice for people online buying drugs or other illicit activities.
Bitcoin’s future in question
No one knows what will become of bitcoin. It is mostly unregulated, but some countries like Japan, China and Australia have begun weighing regulations. Governments are concerned about taxation and their lack of control over the currency.

Academic cryptographer David Chaum had made some progress towards a digital cash system that gave transactional privacy to participants, however there was one major problem with all the known systems at the time. They all had central points of failure which governments could shut down. E-gold, was essentially an anonymous digital cash system that was issued (and backed with physical gold) by a company of the same name. This ended with criminal prosecution of the company’s founders by the US Government as unlicensed money transmitters.client ethereum weekend bitcoin пулы monero bitcoin is bitcoin arbitrage брокеры bitcoin tether bootstrap gui monero ethereum bonus сигналы bitcoin bitcoin cryptocurrency bitcoin asic cryptocurrency market bitcoin anonymous
