Markets are dirty. But this doesn‘t change the fact that cryptocurrencies are here to stay – and here to change the world. This is already happening. People all over the world buy Bitcoin to protect themselves against the devaluation of their national currency. Mostly in Asia, a vivid market for Bitcoin remittance has emerged, and the Bitcoin using darknets of cybercrime are flourishing. More and more companies discover the power of Smart Contracts or token on Ethereum, the first real-world application of blockchain technologies emerge.

Es gibt eine große Vielzahl an verschiedenen Coins und es ist schwierig den Überblick zu behalten, vor allem, weil es beinah jeden Tag neue Kryptowährungen gibt und viele von ihnen schnell wieder verschwinden. Eine Kryptowährung, die sich etabliert hat, ist Ethereum. Laut Wikipedia ist es sogar die Kryptowährung mit der zweitgrößten Marktkapitalisierung überhaupt. Derzeit wird mit großem Eifer an seiner Entwicklung gearbeitet und man darf sich auf die Zukunft von ETH freuen. Aus diesem Grund ist es auch nicht so verrückt, wenn man sich näher mit diesem Coin beschäftigt und sich auch Gedanken macht, ob man Ethereum kaufen sollte.
A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. Many cryptocurrencies are decentralized systems based on blockchain technology, a distributed ledger enforced by a disparate network of computers. A defining feature of a cryptocurrency, and arguably its biggest allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme.[14][15] In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid.[16]
