Dieses dezentrale Konzept verspricht große Anonymität und diverse Sicherheiten. Fällt nämlich ein Server der Netzwerkes aus, kann ein anderer Rechner seine Leistung unmittelbar zur Verfügung stellen. So ist es theoretisch sogar möglich, selbst in die Infrastruktur der Kryptowährungen einzusteigen und eigene Rechnerleistungen und Server bereitzustellen.
Namecoin: In 2015 Namecoin looked promising, here in 2017 there is a little less hype. Still, Namecoin is notable. Namecoin is almost the same as Bitcoin. It was the first “fork” of the Bitcoin software. It’s based on Bitcoin and has the same unit cap, but has a few tweaks in its data storage. Namecoin was originally just going to be an upgrade to Bitcoin, but people were nervous that it would pose issues. So Namecoin is similar to Bitcoin, but like all the currencies that are not-Bitcoin, it is worth a fraction of Bitcoin. Its solid background and reasonable price point make it a relatively good coin to invest in. Of all the coins noted so far, Namecoin has performed the most poorly so far. It is still priced very low in USD.

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.
While cryptocurrencies are digital currencies that are managed through advanced encryption techniques, many governments have taken a cautious approach toward them, fearing their lack of central control and the effects they could have on financial security.[81] Regulators in several countries have warned against cryptocurrency and some have taken concrete regulatory measures to dissuade users.[82] Additionally, many banks do not offer services for cryptocurrencies and can refuse to offer services to virtual-currency companies.[83] Gareth Murphy, a senior central banking officer has stated "widespread use [of cryptocurrency] would also make it more difficult for statistical agencies to gather data on economic activity, which are used by governments to steer the economy". He cautioned that virtual currencies pose a new challenge to central banks' control over the important functions of monetary and exchange rate policy.[84] While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if bitcoins are lost or stolen.[85] One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.

1) Irreversible: After confirmation, a transaction can‘t be reversed. By nobody. And nobody means nobody. Not you, not your bank, not the president of the United States, not Satoshi, not your miner. Nobody. If you send money, you send it. Period. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net.

Below are coins that are no longer on our list of suggestions. They looked great in 2015, but they didn’t stand up over time. Consider we noted Bitcoin, Litecoin, and Dash in 2015, and we noted the coins below. If you invested in them at the time, you did very well. That said, being off the list doesn’t make these coins a bad bet; it just means they aren’t as attractive as they once were:
Michael Casey und Paul Vigna sind erfahrende Finanzjournalisten, die in diesem Buch mit viel Liebe zum Detail Fakten und Geschichten zur kurzen Historie der Krypto-Währungen - angefangen vom Jahr 2008 bis heute - zusammengetragen haben. Sie stellen die treibenden Personen und Unternehmen vor und liefern Einblicke in die Zusammenhänge der verschiedenen Strömungen und Projekte.

In May 2018, Bitcoin Gold (and two other cryptocurrencies) were hit by a successful 51% hashing attack by an unknown actor, in which exchanges lost estimated $18m.[72] In June 2018, Korean exchange Coinrail was hacked, losing US$37 million worth of altcoin. Fear surrounding the hack was blamed for a $42 billion cryptocurrency market selloff.[73] On 9 July 2018 the exchange Bancor had $23.5 million in cryptocurrency stolen.[74]
Bitcoin ist so etwas wie die Mutter aller Kryptowährungen. Sie gibt es mittlerweile seit ca. neun Jahren und interessanterweise weiß man bis heute nicht, wer ihr eigentlicher Gründer ist. Das hat der Nachfrage aber nicht geschadet. Zum Ende des Jahres 2017 sah es sogar kurz danach aus, als würde er die 17500 € Grenze knacken. Leider hat das nicht geklappt und im April 2018 liegt der Kurs bei ca. 5000€.

This flexibility makes Ethereum the perfect instrument for blockchain -application. But it comes at a cost. After the Hack of the DAO – an Ethereum based smart contract – the developers decided to do a hard fork without consensus, which resulted in the emerge of Ethereum Classic. Besides this, there are several clones of Ethereum, and Ethereum itself is a host of several Tokens like DigixDAO and Augur. This makes Ethereum more a family of cryptocurrencies than a single currency.
There is lots of value created by ‘pump- & dumpers’ so watch out! Always set a goal, which you want to achieve, e.g. 2% or 35 USD per day. If you don’t check you exchanges daily, then the best thing you could probably do is add a limit order. A limit order is executed, when a specific price is reached. For example, if you buy Ether for 0.05 BTC. You can make a limit sell order for 0.075 BTC. This means that you will automatically sell your Ether when the value is higher than 0.075 BTC. This assures, that you don’t miss any big price movements- it can always fall back to 0.05 before you can see the profit opportunity.
Ethereum’s average block time is much faster than Bitcoin’s, with Bitcoin running about 10 minutes and Ethereum clocking in at approximately 12 seconds. Cost to transact on Ethereum is also different, with Ethereum calculating the cost based on a term called gas. The amount of gas required for a transaction varies based on storage needs. In contrast, Bitcoin transactions are limited based on block size.
Needless to say, Bitcoin’s place as an alternative digital asset among cryptocurrencies has become entrenched, despite likely headwinds it will continue to face as it evolves further. The U.S. Securities and Exchange Commission (SEC) announced in early August 2017 that certain Initial Coin Offerings (ICOs) – which use cryptocurrencies for financing – would be regulated as securities.

Aber wie sieht die Zukunft des Bitcoin und der Bitcoin-Technologie, der Blockkette, aus, wo liegen die Konfliktlinien? Werden wir weiter in Richtung einer noch stärkeren Zentralisierung in Richtung eines Bankenstaates steuern oder werden sich die libertären Kräfte durchsetzen, die für eine Dezentralisierung eintreten? Die beiden Autoren diskutieren verschiedene Szenarien, wie es weitergehen könnte, wenn alles so weiterläuft wie bisher. Wird sich der Bitcoin als Währung durchsetzen, wird es eine Konkurrenz verschiedener Kryptowährungen geben, wird die Technologie der Blockkette die Basis des Finanzsystems oder werden die Regierungen einfach eigene, zentralisierte, digitale Währungen ausgeben. Beide Autoren kommen aus der klassischen Ökonomie, die permanentes Wachstum im Fokus hat und das hat mir interessante Einblicke verschafft. Zugleich macht es sie aber für radikale Alternativen blind und sie diskutieren weitgehend evolutionäre Prozesse der Anpassung.
Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[25] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[1] This difficulty is derived from leveraging cryptographic technologies.
