Bitcoin and other cryptocurrencies have been identified as economic bubbles by at least eight Nobel Memorial Prize in Economic Sciences laureates, including Robert Shiller,[192] Joseph Stiglitz,[193] and Richard Thaler.[194][13] Noted Keyensian economist Paul Krugman wrote in his New York Times column criticizing bitcoin, calling it a bubble and a fraud;[195] and professor Nouriel Roubini of New York University called bitcoin the "mother of all bubbles."[196] Central bankers, including former Federal Reserve Chairman Alan Greenspan,[197] investors such as Warren Buffett,[198][199] and George Soros[200] have stated similar views, as have business executives such as Jamie Dimon and Jack Ma.[201]

As a cryptocurrency, Bitcoin is generated through the process of "mining"—essentially using your computer's processing power to solve complex algorithms called "blocks." You earn around 50 Bitcoins once a block has been decrypted. The catch? Depending on how powerful your CPU is, solving a single block can take a year or more. Another means of obtaining Bitcoin is to simply buy it, exchanging physical currency for digital at a Bitcoin exchange like Mt. Gox or Bitstamp, or through a service like BitInstant.

One of the most important problems that any payment network has to solve is double-spending. It is a fraudulent technique of spending the same amount twice. The traditional solution was a trusted third party - a central server - that kept records of the balances and transactions. However, this method always entailed an authority basically in control of your funds and with all your personal details on hand.
As you can see, there are many different cryptocurrencies out there and each one of them offers something different. They were all created with certain criteria or functionality in mind, and many more developers continue generating new and improved functions amongst the existing cryptocurrencies, as well as generating new ones to satisfying the ever demanding users.

Bitcoincharts is the most popular website for following the current bitcoin price. The site provides a rundown of all major btc exchanges by volume. You can also arrange the markets to only display the Euro or the Japanese Yen versus bitcoin on the different exchanges. Like the name says, the website also offers charts with several popular technical indicators. The choice of timeframes ranges from 1 minute all the way to the Weekly TF. Plus, you get to see the current market depth at the different exchanges.
Direct trading websites like LocalBitcoins and Paxful connect buyer and seller directly without any additional third parties. The buyer deposits money into the seller's bank account and, upon showing proof, the seller can send the bitcoins from their wallet to the buyer's. Some direct trading sites offer other methods of paying or accepting money, including gift cards and gift card codes, PayPal and Venmo.

It's been sad to watch crypto suffer as much as it has this year, and the worst part is it appears nobody has learned much of anything. Once cryptos usefulness as an endless speculation casino finally dries up (it's getting there), these worthless projects will be all that remains, eternally debating the next hardfork because this developer disagrees over some petty nonsense with another.
But where are the bitcoins actually stored? After you install one of the two clients above, you can find your bitcoins in a file called wallet.dat.

It is always recommend to backup this file.

This cryptocurrency is one of the first ones to hit the market after the launch of Bitcoin. Technically, it is nearly identical to Bitcoin, but with one major difference. Instead of using SHA-256d as its hash algorithm, Litecoin uses Scrypt, created by Colin Percival and designed to make it extremely expensive to initiate large scale hardware attacks because of the amount of memory that is needed to decrypt a single key. Litecoin was released in 2011 and was founded by Charles Lee.

Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people using the name Satoshi Nakamoto[9] and released as open-source software in 2009.[10] Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,[11] products, and services. Research produced by the University of Cambridge estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.[12]
