Als Einstieg wählen sie die Geschichte unseres Währungssystems, die mir die gewachsene Verflechtung von Staat und Banken klar gemacht hat. Sie gehen dann zur Entstehungsgeschichte des Bitcoins über und wie die Gemeinschaft in den ersten Jahren wächst. Wichtige Akteure, mit Ausnahme von Satoshi Nakamoto, dem Begründer des Bitcoin, haben sie direkt befragt, so dass man ein atmosphärisches Bild aus dieser Zeit bekommt. Sie erläutern die Nachteile des „normalen“ Zahlungsverkehrs per Kreditkarte und wie Bitcoin diese Probleme lösen, d.h. das gesamte Prozedere vereinfachen kann. Aber natürlich ist auch Bitcoin nicht die Lösung für alles, denn v.a. fehlt ihm noch das Vertrauen der Menschen als stabile Währung, die unabhängig von einer Regierung funktioniert. Dazu erläutern sie dann die Blockkette, die Technologie hinter allen Kryptowährungen. Diese „block chain“ ist im Grunde eine revolutionäre „Sozialtechnologie“, eine Art digitales, öffentliches Grundbuch, die viele der heutigen „Vertrauenspersonen“ - Banken, Versicherungen, Anwälte, Notare - überflüssig machen könnte. Und nicht nur diese, auch Teile des Regierungsapparates könnten schlicht verzichtbar werden. Sie erläutern, wie diese Blockkette durch das „Schürfen“ („Mining“) öffentlich digital verwaltet wird und gehen dann in den folgenden Kapiteln auf zwei sehr unterschiedliche Aspekte ein. Zum einen beschäftigen sie sich mit den Innovatoren, die das wirtschaftliche Potenzial erkannt haben und mit dieser Technologie reich werden wollen. Zum anderen sehen sie die 2,5 Milliarden Menschen, die kein Bankkonto haben und für Geldtransfers meist 20%, aber gerne auch mal 30% des Überweisungsbetrages abführen müssen. Die Armen in Afrika und Asien, die für Banken wegen ihres geringen Einkommens uninteressant sind, müssen andere Wege finden, um ihr Geld an ihre Familie zu senden und es gibt hier schon seit einigen Jahren spannende Ideen wie M-Pesa, die in einigen Ländern Afrikas Millionen Nutzer haben.

The cryptocurrencies are a solution to many of the obstacles that the traditional financial system currently has, sending money to different parts of the world is expensive, sometimes delayed and in some places it is not possible to do so. We are in a globalized era and cryptocurrencies help make financial transactions fast, secure and low cost. There are projects with a great vision, for example, the cryptocurrency Ultrapoint has the mission to become the first currency for global and practical use in all sectors of the economy. Then when a cryptocurrency achieves massive use, then its benefits will be fully understood.
Within a cryptocurrency network, only miners can confirm transactions by solving a cryptographic puzzle. They take transactions, mark them as legitimate and spread them across the network. Afterwards, every node of the network adds it to its database. Once the transaction is confirmed it becomes unforgeable and irreversible and a miner receives a reward, plus the transaction fees.
Ripple is a real-time global settlement network that offers instant, certain and low-cost international payments. Launched in 2012, ripple “enables banks to settle cross-border payments in real time, with end-to-end transparency, and at lower costs.” Ripple’s consensus ledger (its method of conformation) is unique in that it doesn’t require mining. In this way, ripple sets itself apart from bitcoin and many other altcoins. Since Ripple’s structure doesn't require mining, it reduces the usage of computing power, and minimizes network latency. Ripple believes that “distributing value is a powerful way to incentivize certain behaviors” and thus currently plans to distribute XRP primarily “through business development deals, incentives to liquidity providers who offer tighter spreads for payments, and selling XRP to institutional buyers interested in investing in XRP.” So far, ripple has seen success with this model; it remains one of the most enticing digital currencies among traditional financial institutions looking for ways to revolutionize cross-border payments.
The validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[23][26] Each block typically contains a hash pointer as a link to a previous block,[26] a timestamp and transaction data.[27] By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way".[28] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
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.
Darkcoin (Dash): Darkcoin, known as Dash as of March 25, 2015 (dash=digital cash), but previously known as XCoin, has unique functionality. XCoin was developed by Evan Duffield who wanted to improve on Bitcoin but didn’t have the pull to do so. Thus, he developed his own coin. It takes less power to mine Dash than most coins. Using less energy to mine is important because mining coins is one of the most wasteful processes you can imagine. The wasteful mining process is key to security and stability of all coins that use a “proof-of-work” system. It prevents people from mining too fast. However, environmentally, it’s a nightmare. In 2015 we had said, “People know what a Darkcoin is. Hopefully, this familiarity rolls over to Dash” (today few remember XCoin and Darkcoin, and Dash is a well-known crypto). Back in 2015, Dash was one of the higher valued coins. Today that is still true, and Dash has performed almost as well competitors like Ethereum.
Hier kann man die Plattform kennenlernen, ohne das Risiko eines echten Handels eingehen zu müssen. Der Handelsplattform kommt also eine entscheidende Rolle im Trading zu. Man sollte in seinem persönlichen Test daher nicht vergessen, diese einmal grundlegend auf die Probe zu stellen. Oftmals funktioniert dies sogar ohne echte Anmeldung. Auch Online Vergleiche der verschiedenen digitalen Handelsplattformen sollten aufzeigen, welche spezifischen Eigenschaften die unterschiedlichen Programme innehaben.
Cryptocurrencies hold the promise of making it easier to transfer funds directly between two parties in a transaction, without the need for a trusted third party such as a bank or credit card company; these transfers are facilitated through the use of public keys and private keys for security purposes. In modern cryptocurrency systems, a user's "wallet," or account address, has the public key, and the private key is used to sign transactions. Fund transfers are done with minimal processing fees, allowing users to avoid the steep fees charged by most banks and financial institutions for wire transfers.
TIP: If you don’t understand the tax implications of trading cryptocurrency tread very carefully. There are some nasty traps you could fall into when trading coins. For one, they are not necessarily considered “like-kind assets.” If that is confusing, then consider sticking with trading USD for coins in Coinbase until you grasp the concept. Learn about cryptocurrency and taxes.
In that sense, you can think of Golem as the Airbnb of computing. Just about any situation where heavy computation is necessary – medical research, AI development, computer graphics, cryptography, etc. These are good potential use cases for Golem. All computation is done on virtual machines, so hosts don’t have to sacrifice security to offer their computing power.

Einige User werden auch einen guten Support als besonders wichtig erachten. Zwar sollte man ohnehin eine Vielzahl an Informationen selbst herausfinden können, indem man sich die Plattform näher ansieht, jedoch ist es angenehmer wenn der Broker über einen guten Kundendienst verfügt, welcher es den Nutzern erlaubt auf verschiedene Kommunikationskanäle zugreifen zu können.

To understand the revolutionary impact of cryptocurrencies you need to consider both properties. Bitcoin as a permissionless, irreversible and pseudonymous means of payment is an attack on the control of banks and governments over the monetary transactions of their citizens. You can‘t hinder someone to use Bitcoin, you can‘t prohibit someone to accept a payment, you can‘t undo a transaction.
It would be unfair to make some trading borders for our clients and to make them choose the one exact currency for them to trade. This would cause the huge amount of missed trading opportuninties regarding other cryptocurrencies. That is why we developed the cryptocurrency trading platform which allows to trade on up to 20 different cryptocurrencies. No need to open several accounts for each currency or to make several investments. All you need is just one account for all the trading assets.
Ethereum: Is probably the third most important coin [here in 2018, I’d argue that it is the second most important after Bitcoin]. Ethereum doesn’t have the longevity at the top like Litecoin, but it has some unique features and a market cap that make it a real contender. Most ICOs (Initial Coin Offerings) use Ethereum. It has a less intimidating cost that Bitcoin and has the second highest market cap. On that note, Ethereum classic is also notable. Ethereum is a spin-off (aka “hard fork”) from what isn’t today called Ethereum classic (like how our next up coin, Bitcoin cash, is a spin-off of Bitcoin.) NOTE: Ethereum is a fork of another relevant coin called Ethereum Classic.
