4) “Bitcoin Wastes Energy”
The Bitcoin network currently uses as much energy as a small country. This naturally brings up environmental concerns, especially as it grows.
Similarly, gold mining uses a ton of energy. For each gold coin, a ton of money, energy, and time went into exploration for deposits, developing a mine, and then processing countless tons of rock with heavy equipment to get a few grams of gold per ton. Then, it has to be purified and minted into bars and coins, and transported.
It takes several tons of processed rock to get each 1-ounce gold coin, and thousands of tons of processed rock for each good delivery gold bar. The amount of energy that goes into a small unit of gold is immense.
In fact, that energy is what gives gold value, and what made it internationally recognized as money for thousands of years. Gold is basically concentrated energy, concentrated work, as a dense store of value that does not erode with time.
There’s no limit to how many dollars, euros, or yen we can print, however. Banks multiply them all the time with a stroke of a keyboard. Likewise, industrial metals like iron are very common as well; we have no shortage of them. Gold, however, is very rare, and when found, it takes a ton of energy and time to get into pure form. And then we have to spend more energy transporting, securing, and verifying it from time to time.
However, the world does that anyway, because it derives value from it compared to the value that it had to put in to get it. Gold mining and refining requires energy, but in turn, central banks, institutions, investors, and consumers obtain a scarce store of value, or jewelry, or industrial applications from the rare metal.
Similarly, Bitcoin takes a lot of energy, but that’s because it has so much computing power constantly securing its protocol, compared to countless other cryptocurrencies that are easy to attack or insufficiently decentralized.
Visa uses much less energy than Bitcoin, but it requires complete centralization and is built on top of an abundant fiat currency. Litecoin uses much less energy than Bitcoin as well, but it’s easier for a well-capitalized group to attack.
The question then becomes whether that energy associated with Bitcoin is put to good use. Does Bitcoin justify its energy usage? Does it add enough value?
So far, the market says it does and I agree. A decentralized digital monetary system, separate from any sovereign entity, with a rules-based monetary policy and inherent scarcity, gives people around the world a choice, which some of them use to store value in, and/or use to transmit that value to others.
Those of us in developed markets that haven’t experienced rapid inflation for decades may not see the need for it, but countless people in emerging markets have experienced many instances of severe inflation in their lifetimes, and tend to get the concept more quickly.
Furthermore, a significant portion of the energy that Bitcoin uses could otherwise be wasted. Bitcoin miners seek out the absolute cheapest sources of electricity in the world, which usually means energy that was developed for one reason or another, but that doesn’t currently have sufficient demand, and would therefore be wasted.
Examples of this include over-built hydroelectric dams in certain regions of China, or stranded oil and gas wells in North America. Bitcoin mining equipment is mobile, and thus can be put near wherever the cheapest source of energy is, to arbitrage it and give a purpose to that stranded energy production.
Bitcoin mining converts the output from those cheap stranded sources of energy into something that currently has monetary value.

Until now, cash has been the primary such system. An anonymous transaction system is not a secret transaction system. An anonymous system empowers individuals to reveal their identity when desired and only when desired; this is the essence of privacy. Privacy in an open society also requires cryptography… We cannot expect governments, corporations, or other large, faceless organizations to grant us privacy out of their beneficence. It is to their advantage to speak of us, and we should expect that they will speak. To try to prevent their speech is to fight against the realities of information. Information does not just want to be free, it longs to be free. Information expands to fill the available storage space. Information is Rumor's younger, stronger cousin; Information is fleeter of foot, has more eyes, knows more, and understands less than Rumor. We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do. We the Cypherpunks are dedicated to building anonymous systems. We are defending our privacy with cryptography, with anonymous mail forwarding systems, with digital signatures, and with electronic money.'Cold storage is an offline wallet used for storing bitcoins. With cold storage, the digital wallet is stored on a platform that is not connected to the internet, thereby protecting the wallet from unauthorized access, cyber hacks and other vulnerabilities to which a system that is connected to the internet is susceptible.ethereum habrahabr So those are the details of Bitcoin as a currency unit, but Bitcoin is also a payment network. As a payment network, Bitcoin replaces the function of banks (especially the Federal Reserve as money creation is not at the whim of any person nor group), inter-bank funding networks (like SWIFT and SEPA), payment processors (like PayPal) and remitters (such as Western Union). The entirety of these massive industries as they relate to the creation, storage, accounting, and transfer of money has been usurped by Bitcoin. If Bitcoin succeeds, it is likely that PayPal and Western Union would be removed from the marketplace. The Federal Reserve (and every central bank) would be made redundant. 'Disruptive technology' is thus an understatement.bitcoin community The result of bitcoin mining is twofold. First, when computers solve these complex math problems on the bitcoin network, they produce new bitcoin (not unlike when a mining operation extracts gold from the ground). And second, by solving computational math problems, bitcoin miners make the bitcoin payment network trustworthy and secure by verifying its transaction information.bitcoin satoshi George owes 10 USD to both Michael and Jackson. Unfortunately, George only has 10 USD in his account. He decides to try to send 10 USD to Michael and 10 USD to Jackson at the same time. The bank’s staff notice that George is trying to send money that he doesn’t have. They stop the transaction from happening.bitcoin hacker monero address fee bitcoin today bitcoin nxt cryptocurrency
