Bitcoin is a decentralized digital currency, without a central bank or single administrator, that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain.

Bitcoin is unique in that there are a finite number of them: 21 million.

Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services.

[17] As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.[18].

The European Banking Authority and other sources have warned that bitcoin users are not protected by refund rights or chargebacks because bitcoins are not regulated as financial instruments.[19]

MACD is an indicator that shows the relationship between two moving averages of prices. The MACD is calculated by subtracting the 26-day exponential moving average (EMA) from the 12-day EMA.

A nine-day EMA of the MACD, called the “signal line”, is then plotted on top of the MACD line, which can function as a trigger for buy and sell signals. Traders may buy the currency when it crosses above the signal line and sell – or short – the currency when it crosses below the signal line.
