According to the Bitcoin Energy Consumption Index , Bitcoin mining consumed approximately 51 trillion terawatts of electricity per year as of February This is achieved by slowing, over time, the rate at which the creation of new block chain copies produces new Bitcoin. Every four years or so, this rate halves. The last Bitcoin is projected to spring into being sometime around — that is, if the currency still exists and people still care enough to mine it. This enforced scarcity is a key point of distinction between Bitcoin and traditional fiat currencies, which central banks produce by decree, and supply of which is theoretically unlimited.
In this regard, Bitcoin has more in common with gold than the U. The fact that Bitcoin units are virtually impossible to duplicate does not mean that Bitcoin users are immune to theft or fraud. The Bitcoin system has some imperfections and weak points that can be exploited by sophisticated hackers looking to steal Bitcoin for their own use.
The Mt. In many jurisdictions, Bitcoin occupies a legal gray area, meaning local law enforcement authorities view theft prevention as a relatively low priority. Those who use Bitcoin for illicit purposes face additional risks. Dark web marketplaces — online, international black markets whose users buy and sell illicit substances, stolen goods, and prohibited services — are frequent heist targets. Bitcoin users who participate in the dark web are likely already breaking the law, and thus have limited recourse in the event of a hack or theft.
It usually takes more technical skill to steal Bitcoin than physical cash. Most Bitcoin heists involve sophisticated hack attacks by highly accomplished outsiders or rogue exchange employees. The cybersecurity industry is locked in a constant arms race with hackers and other cyber-criminals, whose sophistication and operational scope increase by the week.
However, prudent Bitcoin users employ these common-sense strategies to reduce their exposure to theft and general security breaches:. Though Bit Gold never gained widespread traction, it shared many features in common with Bitcoin, including ironclad protections against duplication, the block chain as the ultimate transaction ledger, public keys identifying individual users, and built-in scarcity. Bitcoin experienced some growing pains in its first few years of life.

In , Barclays became the first major bank to process Bitcoin transactions, though its embrace was initially limited to charitable contributions. Day traders , hedge funds, and even professional money managers piled into the space, spurring a wave of speculation. As the most popular cryptocurrency by a significant margin, Bitcoin has far greater liquidity than its peers. This allows users to retain most of its inherent value when converting to fiat currencies, such as the U.

Bitcoin transactions that cross international borders are no different from Bitcoin transactions that stay in-country. While most other cryptocurrencies lack international red tape, cross-border Bitcoin transactions are easier simply because Bitcoin is more popular around the world.
Compared to other digital payment methods, such as credit cards and PayPal, Bitcoin comes with lower transaction fees.
Holding U. Many less popular cryptocurrencies are characterized by concentrated holdings — the majority of existing units are held in a handful of accounts. Central banks can create new units of currency at will, and often do — for example, the U.

Though many are structurally quite similar to Bitcoin, others make notable improvements. Some newer cryptocurrencies make it even harder to track money flows or identify users. Some even have in-house exchanges that let users exchange cryptocurrency units directly for fiat currency units, eliminating third-party exchanges and reducing associated fraud risks. Bitcoin mining consumes vast amounts of electricity. According to Business Insider , some of the biggest Bitcoin mining companies are based in China, where most power comes from dirty coal plants and horrific smog routinely makes even low-key outdoor activity unsafe for healthy adults.
