It’s decentralized and brings power back to the people. Launched just a year after the 2008 financial crises, Bitcoin has attracted many people who see the current financial system as unsustainable. This factor has won the hearts of those who view politicians and government with suspicion. It’s no surprise there is a huge community of ideologists actively building, buying, and working in the cryptocurrency world.

Since bitcoin mining has become a hardware intense and therefore expensive process, most individual miners join a so called mining pool. One of the mining pools you can conect to is BitMinter for example. By providing computing power to their pool you can earn Bitcoins from mining without the need to build your own big mining farm. There are entire communities around Bitcoin mining and besides the fact that you earn Bitcoins it's also fun. You meet new people online and get in-depth knowledge about Bitcoin as a protocol and technology.
Blockchain forms the bedrock for cryptocurrencies like Bitcoin. As we explored earlier, currencies like the U.S. dollar are regulated and verified by a central authority, usually a bank or government. Under the central authority system, a user’s data and currency are technically at the whim of their bank or government. If a user’s bank collapses or they live in a country with an unstable government, the value of their currency may be at risk. These are the worries out of which Bitcoin was borne. By spreading its operations across a network of computers, blockchain allows Bitcoin and other cryptocurrencies to operate without the need for a central authority. This not only reduces risk but also eliminates many of the processing and transaction fees. It also gives those in countries with unstable currencies a more stable currency with more applications and a wider network of individuals and institutions they can do business with, both domestically and internationally (at least, this is the goal.)
Remember that "Bitcoin exchange" and "Bitcoin wallet" need not be the same. Bitcoin exchanges are kind of like foreign exchange markets – places where you can trade Bitcoin for a fiat currency, say, BTC for USD and vice versa (in U.S. for example). While exchanges offer wallet capabilities to users, it’s not their primary business. Since wallets need to be kept safe and secure, exchanges do not encourage storing of Bitcoins for higher amounts or long periods of time. Hence, it is best to transfer your Bitcoins to a secure wallet. Security must be your top priority while opting for a Bitcoin wallet; always opt for the one with multi-signature facility.
In Charles Stross' 2013 science fiction novel, Neptune's Brood, the universal interstellar payment system is known as "bitcoin" and operates using cryptography.[227] Stross later blogged that the reference was intentional, saying "I wrote Neptune's Brood in 2011. Bitcoin was obscure back then, and I figured had just enough name recognition to be a useful term for an interstellar currency: it'd clue people in that it was a networked digital currency."[228]
Now to get the blockchain explained in simple words, it requires no central server to store blockchain data, which means it is not centralized. This is what makes the blockchain so powerful. Instead of the server being stored in one place, it is stored on the blockchain and is powered by many different computers/nodes. This means there is no third party to trust and pay a fee to.
If the private key is lost, the bitcoin network will not recognize any other evidence of ownership;[31] the coins are then unusable, and effectively lost. For example, in 2013 one user claimed to have lost 7,500 bitcoins, worth $7.5 million at the time, when he accidentally discarded a hard drive containing his private key.[76] A backup of his key(s) would have prevented this.
Derivatives are used in stock exchanges and are concerned with the values of assets. Smart contracts in the trading of stocks and shares could revolutionize current practices by streamlining, automating and reducing the costs of derivatives trading across the industry. Settlements could be completed in seconds rather than the three days that are needed at present. Using smart contracts, peer-to-peer trading will become a usual operation, resulting in a complete revolution in stock trading. Barclays and several other companies has already trialed a way of trading derivatives using smart contracts, but they came to the conclusion that the technology won’t work unless banks collaborate to implement it.
Bitcoin has come far in a relatively short time. All over the world, companies, from REEDS Jewelers, a large jewelry chain in the US, to a private hospital in Warsaw, Poland, accept its currency. Billion dollar businesses such as Dell, Expedia, PayPal, and Microsoft do, too. Websites promote it, publications such as Bitcoin Magazine publish its news, forums discuss cryptocurrency and trade its coins. It has its application programming interface (API), price index, and exchange rate.
Although transactions are publicly recorded on the blockchain, user data is not — or, at least not in full. In order to conduct transactions on the Bitcoin network, participants must run a program called a “wallet.” Each wallet consists of two unique and distinct cryptographic keys: a public key and a private key. The public key is the location where transactions are deposited to and withdrawn from. This is also the key that appears on the blockchain ledger as the user’s digital signature.

Illiquidity. This is mostly moot due to Bitcoin’s $47 market cap but it still makes users sweat. It’s highly unlikely that Bitcoin’s price would plummet and you’d be unable to take action, but it’s still unsettling.  As more investors invest, however, illiquidity becomes a negligible risk, as there will likely always be a buyer for Bitcoins waiting.
You also have private blockchains. These are often used for more niche purposes like a business managing data or interacting with its customers. For example, Northern Trust, the financial services firm created one with IBM that it’s been testing for more than a year to store data such as biometric information and other records. In June, it also won a patent for storing meeting notes on the blockchain.
Plus, dealing with the IRS if you accept a lot of bitcoin in exchange for your goods and services might be more complicated than you want. Technically, the IRS sees bitcoin as a property, not a currency. This can get messy, since a bitcoin exchange can involve a gain or a loss in U.S. dollars, even if you’re gaining bitcoins. Talk to your accountant before diving into the world of bitcoin, and keep an eye out for future developments regarding bitcoin regulation.
Every 2,016 blocks (approximately 14 days at roughly 10 min per block), the difficulty target is adjusted based on the network's recent performance, with the aim of keeping the average time between new blocks at ten minutes. In this way the system automatically adapts to the total amount of mining power on the network.[3]:ch. 8 Between 1 March 2014 and 1 March 2015, the average number of nonces miners had to try before creating a new block increased from 16.4 quintillion to 200.5 quintillion.[84]
