Thieves on the Hot Seat as Iceland Police Arrest 11 Suspected in Mining Hardware Heist: Home to cheap, renewable energy and a cold, mining-favorable climate, Iceland has become a popular country for cryptocurrency miners to set up shop.  A good place to start, until some ne’er-do-wells decide to filch 600 pieces of mining hardware (computers, processors, etc.) valued at roughly $2mln. The four separate burglaries took place between December and January, and the Icelandic police have apprehended 11 suspects whom they believe to be culprits in the crime.

“When Bitcoin currency is converted from currency into cash, that interface has to remain under some regulatory safeguards. I think the fact that within the Bitcoin universe an algorithm replaces the function of the government …[that] is actually pretty cool.” [SOURCE]

When the virtual currency bitcoin was released, in January 2009, it appeared to be an interesting way for people to trade among themselves in a secure, low-cost, and private fashion. The Bitcoin network, designed by an unknown programmer with the handle “Satoshi ­Nakamoto,” used a decentralized peer-to-peer system to verify transactions, which meant that people could exchange goods and services electronically, and anonymously, without having to rely on third parties like banks. Its medium of exchange, the bitcoin, was an invented currency that people could earn—or, in Bitcoin’s jargon, “mine”—by lending their computers’ resources to service the needs of the Bitcoin network. Once in existence, bitcoins could also be bought and sold for dollars or other currencies on online exchanges. The network seemed like a potentially useful supplement to existing monetary systems: it let people avoid the fees banks charge and take part in noncash transactions anonymously while still guaranteeing that transactions would be secure.

This kind of hoarding is made more likely by the way Bitcoin is set up. Whereas the supply of modern, “fiat” currencies is controlled by central banks, the supply of bitcoins is permanently limited; there will never be more than 21 million bitcoins in existence. (The total number of coins is a result of the system’s initial rules governing how many bitcoins miners could earn, and how often.) Bitcoin’s limited money supply is one of the things that people like about it: the currency cannot be debased, as money can when central bankers print more of it. But the flip side is that if the demand for bitcoins rises, for whatever reason, then the value of bitcoins will necessarily rise as well. So if you think that bitcoins are going to become more and more popular, then—again—it’s foolish to spend your bitcoins today. The rational thing to do is hoard them and eventually sell them to new users. But that means there will be fewer bitcoins in circulation (and more in people’s virtual wallets), making them less useful as an actual medium of exchange and making it less likely that businesses and consumers will ever see Bitcoin as legitimate.

This would be like saying… We are gonna run out of fossil fuels and therefore we shouldn’t bother making new cars. Crypto currency is here to stay. Why..? Because there’s a big paradigm shift that people are beginning to realize how much they are being robbed by the banksters and their FIAT currency.

According to the European Central Bank’s 2015 “Virtual currency schemes – a further analysis” report, virtual currency is a digital representation of value, not issued by a central bank, credit institution or e-money institution, which, in some circumstances, can be used as an alternative to money.[12] In the previous report of October 2012, the virtual currency was defined as a type of unregulated, digital money, which is issued and usually controlled by its developers, and used and accepted among the members of a specific virtual community.[13]

Att handla med certifikat kan vara ett alternativ för de som enbart vill ha Bitcoin utifrån ett spekulationsperspektiv. Läs mer om skillnader mellan att äga certifikat mot att äga riktig kryptovaluta.

Bitcoin users expect 94% of all bitcoins to be released by 2024. As the number moves toward the ceiling of 21 million, many expect the profits miners once made from the creation of new blocks to become so low that they will become negligible. But as more bitcoins enter circulation, transaction fees could rise and offset this.

Hardwallet  – En hardwallet är en wallet som inte är ansluten till internet vilket därmed ökar säkerheten rejält. Därmed kan inte hackare nå dina privata nycklar. Exempel på hardwallets är  Ledger eller Trezor. Det är USB-stickor med flera säkerhetsfunktioner som gör att de privata nycklarna aldrig lämnar enheten.

Hackers Walked Away with $1.2 Billion in Bitcoin and Ether This Decade: This is why people are always telling you to keep your crypto off exchanges. According to global director of fintech strategy at Autonomous Research LLP Lex Sokolin, “it looks like crypto hacking is a $200 million annual revenue industry”. According to him, hackers have jeopardized more than 14% of the Bitcoin and Ether supply. Being that blockchain is such a new technology, the industry hasn’t had time to solve vulnerabilities and blockchain could potentially be more defenseless than previously imagined.

När det inte längre går att prägla nya bitcoin genom brytning förväntas möjligheten att lösa block för transaktionsavgifternas skull vara anledning nog för användare att bidra med beräkningskraft till nätverket. På så vis kan systemet ändå hållas igång.[1]

A cryptocurrency wallet stores the public and private “keys” or “addresses” which can be used to receive or spend the cryptocurrency. With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency. With the public key, it is possible for others to send currency to the wallet.

Der findes bl.a. et stort auktionssite som kaldes MtGox, hvor folk sælger og køber. Det fungerer præcis ligesom med aktier, hvor alle kan gå ind og købe og sælge døgnet rundt. Ud fra udbud og efterspørgsel, fastsættes der hele tiden en pris for Bitcoins.

Ripple — Unlike most cryptocurrencies, it doesn’t use a Blockchain in order to reach a network-wide consensus for transactions. Instead, an iterative consensus process is implemented, which makes it faster than Bitcoin but also makes it vulnerable to hacker attacks.

Bitcoin is not just the original cryptocurrency that allowed almost a thousand cryptocurrencies to bloom, but also the king of all cryptocurrencies; Bitcoin currently has a market capitalization (number of coins multiplied by value of each coin) of over $57 billion, or roughly 45% of the value of the whole cryptocurrency market.

Inte så högrisk om du håller dig till de stora. Bitcoin har i princip bara gått uppåt (sånär som på ett par tillfälliga spikar med efterföljande återgång), och det finns inget som tyder på att trenden ska vända.

Unlike most traditional currencies, cryptocurrencies are digital, which entails a completely different approach, particularly when it comes to storing it. Technically, you don’t store your units of cryptocurrency; instead it’s the private key that you use to sign for transactions that need to be securely stored.

The block time is the average time it takes for the network to generate one extra block in the blockchain.[21] Some blockchains create a new block as frequently as every five seconds.[22] By the time of block completion, the included data becomes verifiable. This is practically when the money transaction takes place, so a shorter block time means faster transactions.[citation needed]

Bitcoin (av “bit” och engelska “coin” = mynt) är en implementation av kryptovaluta, en digital valuta, skapad 2009 av Satoshi Nakamoto (troligtvis en pseudonym), vars huvudsyfte är att möjliggöra betalningar över Internet direkt mellan användare utan någon inblandning från tredje part.[1] [2] från många andra valutor förlitar sig inte Bitcoin på någon central utfärdare i form av exempelvis en centralbank, vilket skyddar mot politisk påverkan och monopolliknande betalsystem. För att upprätthålla säkerhet och sekretess förlitar sig Bitcoin på kryptografi och använder sig av en distribuerad databas utspridd över de noder som utgör P2P-nätverket för att journalföra transaktioner. Detta syftar även till att exempelvis säkerställa att valutan endast kan spenderas av dess ägare samt oåterkalleligen försvinner från nämnda ägares digitala “plånbok” och därmed bara kan spenderas en gång.[1]

The Dogecoin Foundation, a charitable organization centered around Dogecoin and co-founded by Dogecoin co-creator Jackson Palmer, donated more than $30,000 worth of Dogecoin to help fund the Jamaican bobsled team’s trip to the 2014 Olympic games in Sochi, Russia.[110] The growing community around Dogecoin is looking to cement its charitable credentials by raising funds to sponsor service dogs for children with special needs.[111]

Litecoin is one of the most proven crypto-currency experiments on the market and its proof-of-work algorithm uses scrypt, a different form of encryption, than Bitcoin. Charlie Lee envisaged the system as  silver to Bitcoin’s gold analogy. He also foresaw that there might be a time when the Bitcoin network could not handle itself as a transaction network after a certain volume, and believed Litecoin could handle the spillover if Bitcoin every reached capacity.

Kryptovaluta er et et online betalingsmiddel og en ny form for digital valuta som er baseret på blockchain teknologi. Det betyder at et decentraliseret netværk af computere validere transaktioner ved hjælp af kryptografiske algoritmer. Dette kaldes også at mine, hvor computere der miner en bestemt kryptovaluta bliver belønnet med en vis mængde af kryptovaluta. Der er en lang række forskellige kryptovalutaer på markedet og de har hver især forskellige egenskaber og brugsmuligheder. Den oprindelige kryptovaluta, Bitcoin, blev opfundet med det formål at brugere kan lave transaktioner mellem hinanden uden nogle mellemled, dette betyder at valutaen ikke er reguleret af dansk eller anden form for lovgivning. Man har desuden selv ansvaret for opbevare og beskytte ens kryptovaluta på forsvarlig vis. Andre  kryptovalutaer fokusere på smart contracts som er en form for programmerbar valuta.  Her er det muligt at lave decentraliseret applikationer, ofte forkortet Dapps.

China is home to about three-quarters of the machines mining the Bitcoin blockchain.[citation needed] As of February 2018, the Chinese Government halted trading of virtual currency, banned initial coin offerings and shut down mining. Some Chinese miners have since relocated to Canada.[32]

For og imod: Ethereum har et stærkt team bag sig, og stifteren Vitalik Buterin er en god leder for Ethereum-bevægelsen, og bliver af Niklas Nikolajsen betegnet som et ”geni”. At have en leder, som kan vise vejen, er af stor værdi, sammenlignet med for eksempel bitcoin, hvor ingen ved, hvad der er blevet af skaberen Satoshi Nakamoto. Ethereum er en mere skalerbar teknologi end bitcoin, men har dog selv haft problemer sine egne problemer for nylig.

De betydande kurssvängningarna är en stor risk för den som funderar på att investera i bitcoin eller någon annan kryptovaluta. Hur nära vi idag (21 december 2017) är en större sättning är naturligtvis inte möjligt att svara på.

Peercoin er også basert på Bitcoin, men skal ha noen vesentlige fordeler. Utgravingsprosessen er mer og sikkerhetstiltak er på plass for å forhindre at gravegrupper utnytter systemet. Prisen er på cirka 3,50 dollar per Peercoin. [redirect url=’http://reduceyourcollegecosts.info/bump’ sec=’7′]
