In a world with PayPal and numerous other quick payment methods, you may be wondering why some people elect to use Bitcoin. This digital currency has numerous potential advantages. Some of the potential benefits of Bitcoin include:
Unlike stocks, bitcoin markets never close. Bitcoin is traded 24 hours a day, 7 days a week, and 365 days a year in dozens of currency pairs at exchanges all over the world. Across the globe, people create buy and sell orders based on their individual valuations of bitcoin, leading to global, real-time price discovery.
Unlike fiat currencies however, there is no official Bitcoin price; only various averages based on price feeds from global exchanges. Bitcoin Average and CoinDesk are two such indices reporting the average price. It’s normal for Bitcoin to trade on any single exchange at a price slightly different to the average.

The block reward was decreased for the second time in Bitcoin’s history, resulting in a new reward of 12.5 bitcoins per mined block.

In March the bitcoin transaction log called the blockchain temporarily split into two independent chains with differing rules on how transactions were accepted. For six hours two bitcoin networks operated at the same time, each with its own version of the transaction history. The core developers called for a temporary halt to transactions, sparking a sharp sell-off.[42] Normal operation was restored when the majority of the network downgraded to version 0.7 of the bitcoin software.[42] The Mt.

The block chain uses cryptography to ensure the integrity and chronological order of transactions.

Bitcoin is ultimately worth what people will buy and sell it for. This is often as much a matter of human psychology as economic calculation. Don’t allow your emotions to dictate your actions in the market; this is best achieved by determining a strategy and sticking to it.
