An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017.[37] Popular favorites of cryptocurrency miners such as Nvidia's GTX 1060 and GTX 1070 graphics cards, as well as AMD's RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[38] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.[39]

As described in their whitepaper, Augur has set out to create the first decentralized, open-source platform for prediction markets. Based on the ideas of game theory and wisdom of the crowd, prediction markets achieve greater forecasting accuracy than any individual experts can. However, the problem with previously existing prediction markets is that they were all centralized.
Essentially, any cryptocurrency network is based on the absolute consensus of all the participants regarding the legitimacy of balances and transactions. If nodes of the network disagree on a single balance, the system would basically break. However, there are a lot of rules pre-built and programmed into the network that prevents this from happening.
Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain.[29] Blockchains solve the double-spending problem without the need of a trusted authority or central server, assuming no 51% attack (that has worked against several cryptocurrencies).
Dear Ladies And Gentlemen! Let me start telling you, that even though I believe we will go down short term, we are having a bullish Global Market Sentiment. I will claim, that it's likely that we will enter a BULL MARKET within 3 months. Here are the reasons - we have for a long time seen: -Increasing Global Market Cap -Dropping BTC-Dominance -Increasing...

You don‘t need to understand details about SHA 256. It‘s only important you know that it can be the basis of a cryptologic puzzle the miners compete to solve. After finding a solution, a miner can build a block and add it to the blockchain. As an incentive, he has the right to add a so-called coinbase transaction that gives him a specific number of Bitcoins. This is the only way to create valid Bitcoins.
Der Punkt ist aber, dass es mit hoher Wahrscheinlichkeit nicht so weitergehen wird wie bisher. Als Journalisten, die für die Presse-Flaggschiffe des westliche Finanzsystems arbeiten, berufen sie sich gerne auf „Experten“, die eine weitere Krise für unvermeidlich halten. Das weiß aber im Grunde jeder, der seine Augen offen hält. Ein Crash könnte der Durchbruch für den Bitcoin, zumindest aber für die Technologie dahinter werden. Satoshi Nakamoto schickte sein mittlerweile berühmtes White Paper zum Bitcoin am 31.10.2008 in die Welt, im April 2011 kam seine letzte Email und seitdem schweigt er und niemand weiß, wer er ist. Es gibt klare Hinweise darauf, dass sein Bitcoin-Entwurf eine direkte Reaktion auf die Finanzkrise 2008 war. Einmal ist ihm ein Geniestreich gelungen, vielleicht gelingt ihm ein zweiter, wenn er in der nächsten Krise seine eigene Million Bitcoins (von den insgesamt 14,16 Mio. Bitcoins - Stand Mai 2015) klug einsetzt.
I want to begin with the following statement: I have never relied on fractals and preferred to argue based on Oscillators and popular TA Patterns. Moreover, I always try to look at the market situation, imagining myself as a market maker (MM) and choose the most suitable combination of actions to take more money from liquidations. However, we all know how...
This mega-powerful currency has not only opened the gate for other currencies, but also leads the cryptocurrency world with pride. It is governed to make sure no extra Bitcoin is produced, as a maximum quantity of 21 Million Bitcoin units was agreed. When introduced, the price of $1 was 1,309 BTC. The wheel has turned and when Bitcoin breached the $2,000 barrier in 2017, meaning 1 BTC was worth $2,000, it was certainly a meaningful milestone to Satoshi Nakamoto, the creator of Bitcoin.
Peercoin: Like Nxt, Peercoin (abbreviated PPC) uses a proof-of-stake system; in fact, it was the first proof-of-stake coin. It’s worth about $0.40 on the USD and has a market cap of almost ten million. This coin has everything going for it and might be a smart bet as far as cryptocurrency goes. As an bonus to the confidence and quality of the coin, Peercoin was developed by Sunny King. Sunny King is, or might be, the person who created Bitcoin or another coin, or maybe Bruce Wayne or Clark Kent. It’s hard to tell as the culture of cryptocurrency puts importance on peer-to-peer, code, and coin over developers. Still, he is important, and like-it-or-not little things like this could be the deciding factor in whether a coin sinks or swims in the new market. Peercoin has a story like Nxt and Namecoin where they are long-running coins.

Digital currency puts the power back in the hands of the user and breaks free of centralized and governing agencies. You own the private and public keys that make up your address - and nobody can take them away from you. Selecting the right option, however, depends on how you will use it. For some, you need to crowdsource or create contracts, and for others, it’s purely transactional. By understanding the benefits of each option and matching the right ones to your needs, you can make a more informed choice. We hope this list of cryptocurrencies has been informative, make sure to check out our other blog posts for more info on how cryptocurrency works!
Aus meiner Sicht besonders spannend sind die Kapitel zu den weiteren Anwendungsmöglichkeiten, die sich aus dem Blockchain-Konzept für ein "automatisiertes Vertrauen" ergeben. Die Konsequenz, darüber nachzudenken, wofür wir in Zukunft Vertrauensvolle (zentrale) Instanzen benötigen und wo und wie wir Vertrauen algorithmisch (dezentral) abbilden können, finde ich absolut faszinierend. Es geht also nicht nur bei Banken und in der Finanzwelt um die Fragen „zentral oder dezentral“, „Torwächter oder Macht“, sondern auch in vielen anderen Branchen. - Eine absolute Leseempfehlung!
In 1998, Wei Dai published a description of "b-money", characterized as an anonymous, distributed electronic cash system.[12] Shortly thereafter, Nick Szabo described bit gold.[13] Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.[citation needed]
