While there is certainly the possibility of making short-term profits in Bitcoin, many market participants are viewing an investment in Bitcoin as a long-term play. If the cryptocurrency were to eventually become a favored form of global payment and remittance, there is no telling just how high prices could go. Some have even suggested that the price of Bitcoin could hit $50,000 in 2018 and eventually $1 million.

A wallet stores the information necessary to transact bitcoins. While wallets are often described as a place to hold[87] or store bitcoins,[88] due to the nature of the system, bitcoins are inseparable from the blockchain transaction ledger. A better way to describe a wallet is something that "stores the digital credentials for your bitcoin holdings"[88] and allows one to access (and spend) them. Bitcoin uses public-key cryptography, in which two cryptographic keys, one public and one private, are generated.[89] At its most basic, a wallet is a collection of these keys.
The initialization process is relatively simple. Plug it into a USB port on your device. You will then have to generate a private key by adding 256 KB to the drive. You can do this by dragging one or two random pictures into it. After the private key is generated the drive will self-eject. It is now ready to use. To manage your assets and view your digital address you will have to open the index.htm file located on the drive. The user interface is very easy to use and even provides links to several blockchain browsers.
So that’s Bitcoin mining in a nutshell. It’s called mining because of the fact that this process helps “mine” new Bitcoins from the system. But if you think about it, the mining part is just a by-product of the transaction confirmation process. So the name is a bit misleading, since the main goal of mining is to maintain the ledger in a decentralized manner.
A $720 million sleeping giant has woken up after four years, with $100 million moved to Bitfinex and Binance over the course of ten days at the end of August. The bitcoin wallet contains 111,114 BTC or 0.52% of the total supply. The sudden movement of these dormant funds could have a disruptive potential in the market price action, particularly if the funds belong to one of the two possible likely candidates suggested by Reddit sleuth u/sick_silk.
Several news outlets have asserted that the popularity of bitcoins hinges on the ability to use them to purchase illegal goods.[27][28] In 2014, researchers at the University of Kentucky found "robust evidence that computer programming enthusiasts and illegal activity drive interest in bitcoin, and find limited or no support for political and investment motives."[29]
The proof-of-work system, alongside the chaining of blocks, makes modifications of the blockchain extremely hard, as an attacker must modify all subsequent blocks in order for the modifications of one block to be accepted.[81] As new blocks are mined all the time, the difficulty of modifying a block increases as time passes and the number of subsequent blocks (also called confirmations of the given block) increases.[64]
Benny: The Rogue Miner “Benny,” a self-taught, 20-something computer whiz, set up three mining servers in his Wenatchee home last summer. Since then he has made enough profit not only to recover his initial investment but also to pay his monthly mortgage. As a bonus, the heat from the computers keeps his home heated all winter. “It’s just basically free money,” says Benny, pictured here with his homemade mining operation. | Patrick Cavan Brown for Politico Magazine
Keeping your Bitcoin wallet safe is essential as Bitcoin wallets represent high-value targets for hackers. Some safeguards include: encrypting the wallet with a strong password, and choosing the cold storage option i.e. storing it offline. It's also advisable to frequently back up your desktop and mobile wallets, as problems with the wallet software on your computer or mobile device could erase your holdings. 
For years, few residents really grasped how appealing their region was to miners, who mainly did their esoteric calculations quietly tucked away in warehouses and basements. But those days are gone. Over the past two years, and especially during 2017, when the price of a single bitcoin jumped from $1,000 to more than $19,000, the region has taken on the vibe of a boomtown. Across the three rural counties of the Mid-Columbia Basin—Chelan, Douglas and Grant—orchards and farm fields now share the rolling landscape with mines of every size, from industrial-scale facilities to repurposed warehouses to cargo containers and even backyard sheds. Outsiders are so eager to turn the basin’s power into cryptocurrency that this winter, several would-be miners from Asia flew their private jet into the local airport, took a rental car to one of the local dams, and, according to a utility official, politely informed staff at the dam visitors center, “We want to see the dam master because we want to buy some electricity.”
There are many Bitcoin supporters who believe that digital currency is the future. Those who endorse it are of the view that it facilitates a much faster, no-fee payment system for transactions across the globe. Although it is not itself any backed by any government or central bank, bitcoin can be exchanged for traditional currencies; in fact, its exchange rate against the dollar attracts potential investors and traders interested in currency plays. Indeed, one of the primary reasons for the growth of digital currencies like Bitcoin is that they can act as an alternative to national fiat money and traditional commodities like gold.
In 2014 prices started at $770 and fell to $314 for the year.[31] In February 2014 the Mt. Gox exchange, the largest bitcoin exchange at the time, said that 850,000 bitcoins had been stolen from its customers, amounting to almost $500 million. Bitcoin's price fell by almost half, from $867 to $439 (a 49% drop). Prices remained low until late 2016.[citation needed]
