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!

Cryptocurrencies are encrypted digital currencies which are transferred between peers. They are decentralized, meaning not governed by any bank or government institution. They are a sequence of encrypted codes transmitted and stored over a network. All transactions are confirmed and stored on a public ledger. The system uses other complex techniques to certify and validate the record keeping process. Lack of regulation for cryptocurrencies mean that they are highly volatile by nature, and an investment with this can make a lot of money fast, and at the same time it can turn and one can lose money fast. The reason it is not yet accepted by a lot of businesses is partly due to the lack of regulation. There is a set amount of digital coins that can be created and which was outlined from the beginning, after that number is reached no further coins can be produced. The reality is such, that Bitcoin and digital currencies prices rise and drop for various reasons such as media and bad press, news events, and government statements, more people are using it and for this reason the price is rising. Their unpredictability makes it exciting for most traders. Moving forward there are discussions on how to manage the currencies and that in itself can swing the price.

A lot of people have made fortunes by mining Bitcoins. Back in the days, you could make substantial profits from mining using just your computer, or even a powerful enough laptop. These days, Bitcoin mining can only become profitable if you’re willing to invest in an industrial-grade mining hardware. This, of course, incurs huge electricity bills on top of the price of all the necessary equipment.

Casey und Vigna sind Wirtschaftsjournalisten, die regelmäßig für die Financial Times, die Washington Post, für das Wall Street Journal und CNN und BBC arbeiten. Mehr an klassischer Ökonomie geht fast nicht mehr: „Wir waren beiden Skeptiker, als wir von Bitcoin hörten. Geld, das nicht vom Staat garantiert wird? Verrückt!“ Aber sie sind neugierig und beiden steckt noch der Crash von 2008 in den (Schädel-)knochen. Sehr nachvollziehbar beschreiben sie die Phasen der Akzeptanz von Geringschätzung über Skepsis, Neugier bis hin zum Moment „wo der Groschen fällt“, wo sie „plötzlich eine Vorstellung von einer ganz neuen Art, Dinge zu tun“ haben bis hin zur Akzeptanz. Das Buch ist eine Entdeckungsreise in die Welt der Krytowährungen und der Technologie dahinter und sie versuchen, die vielen Puzzelteile zusammenzusetzen. Das ist ihnen nicht nur gelungen, sie haben es in einer Sprache geschrieben, die jeder verstehen kann. Aus meiner Sicht ist es derzeit das Standardwerk, einfach guter Journalismus.
NEM (New Economy Movement) is the world’s first Proof-of-Importance (PoI) enterprise based on blockchain technology. With a focus on business use cases, the software was built from the ground up with adaptability in mind. NEM’s goal is for companies to use their “smart asset system” to implement customizable blockchains. A smart asset can be almost anything: a cryptocurrency token, a business’s stock or a company’s invoicing and records.
How does the flow of Cryptocurrency handled? How is the ratio between supply and demand balanced? I have read that there has been times when the security of crypto-network has been compromised. Is it really the future of Digital Money? Rather than a currency, it seems to be an investment scheme plan. I am not trying to be a critic here, just a lot of questions bubbling into the mind.

When issuing a transaction in IOTA, you validate 2 previous transactions. This means you no longer outsource validation to miners which requires wasteful amounts of computing power and usually a large stake of coins. These required resources are, in effect, centralizing the currencies which many believe were created to be decentralized in the first place.  
There are also purely technical elements to consider. For example, technological advancement in cryptocurrencies such as bitcoin result in high up-front costs to miners in the form of specialized hardware and software.[87] Cryptocurrency transactions are normally irreversible after a number of blocks confirm the transaction. Additionally, cryptocurrency private keys can be permanently lost from local storage due to malware, data loss or the destruction of the physical media. This prevents the cryptocurrency from being spent, resulting in its effective removal from the markets.[88]
For those who really want the real cryptocurrency experience, I think the simplest place to buy, sell, and store coins is Coinbase (and our tutorial below will help you get set up with that), but you can only buy, sell, and store Bitcoin, Ethereum, Litecoin, Bitcoin Cash, and a small (but growing) selection of other coins on Coinbase. However, if you are serious about trading cryptocurrency, you’ll want to also sign up for another exchange like Coinbase’s Coinbase Pro, Bittrex, Binance, or Kraken (and may want to find other solutions for wallets to store your coins in like TREZOR). See our list of exchanges for beginners for a more complete list. TIP: Even if you are going to get fancy with wallets and exchanges, Coinbase is a good starting point because it works as a simple on-ramp / off-ramp for fiat (i.e. you can easily trade dollars for cryptos on Coinbase, and this is not true of most exchanges).

Cryptocurrency exchanges are websites where you can buy, sell or exchange cryptocurrencies for other digital currency or traditional currency like US dollars or Euro. For those that want to trade professionally and have access to fancy trading tools, you will likely need to use an exchange that requires you to verify your ID and open an account. If you just want to make the occasional, straightforward trade, there are also platforms that you can use that do not require an account.
TIP: There are a few sides to cryptocurrency. 1. you can trade and invest in it, 2. you can use it for transactions (anywhere a coin type is accepted), 3. you can break out a graphics processing unit and some software and mine coins (see how to mine coins), 4. you can develop for it, etc. All those and more are valid and interesting ways to interact with the crypto space, but with that in mind, this page is focused on “trading” cryptocurrency (and therefore also investing in it). With that said, even if you want to do the other things with cryptocurrencies, you still need to be set up for trading (as for example most miners will sell at least some of the coins they mine and developers will need to fund their operations).
The price is trying to break the downtrend line and the resistance zone between 4200.00 and 4300.00 levels. RSI and MACD histogram support the upward movement. DMI becomes bullish. ADX line is below the signal level but it looks like it will move upward. We are going to get a breakout. But for this, the close price will need to stay above the uptrend line at...

There are several different types of cryptocurrency wallets that cater for different needs. If your priority is privacy, you might want to opt for a paper or a hardware wallet. Those are the most secure ways of storing your crypto funds. There are also ‘cold’ (offline) wallets that are stored on your hard drive and online wallets, which can either be affiliated with exchanges or with independent platforms.
According to the graphs, we determine whether the value of the currency is going to decline or rise. Graphs can be different in appearance. For example, some display changes at 15-minute intervals, and some changes occur once a day. Orders are, roughly speaking, user requests for the purchase or sale of currency. According to the history of transactions, you can track what transactions were conducted on the exchange recently and with what tools. By the volume of trade, it is possible to judge which mass of the crypto currency has passed from one source to another in a certain period of time.
Transaction fees for cryptocurrency depend mainly on the supply of network capacity at the time, versus the demand from the currency holder for a faster transaction. The currency holder can choose a specific transaction fee, while network entities process transactions in order of highest offered fee to lowest. Cryptocurrency exchanges can simplify the process for currency holders by offering priority alternatives and thereby determine which fee will likely cause the transaction to be processed in the requested time.
