If you decide to invest in cryptocurrencies, Bitcoin is obviously still the dominant one. However, in 2017 its share in the crypto-market has quite dramatically fallen from 90 percent to just 40 percent. There are many options currently available, with some coins being privacy-focused, others being less open and decentralized than Bitcoin and some just outright copying it.


Americ, your insights were very informative! A few months ago I didn’t even know what blockchain is, only heard about cryptocurrencies. My friend suggested me to start an investigation on crypto-mining, there was a boom of articles, but in most cases highly generic ones. Thus my friend found BitDegree publishing lots of good stuff about the crypto world, and especially the whole tutorials about mining that helped us to our Litecoin mining career step-by-step!

One of the key differences between 0x and other decentralized exchanges is that 0x is fast. To reduce blockchain bloat, all orders are transported off-blockchain and later verified. In addition to making transactions quick, this removes the necessity of spending gas to pay for network transaction costs, like on other decentralized exchanges such as EtherDelta.
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.
A digital currency exchange can be a brick-and-mortar business or a strictly online business. As a brick-and-mortar business, it exchanges traditional payment methods and digital currencies. As an online business, it exchanges electronically transferred money and digital currencies.[1] Often, the digital currency exchanges operate outside the Western countries to avoid regulation and prosecution. However, they do handle Western fiat currencies and maintain bank accounts in several countries to facilitate deposits in various national currencies.[2][3] Exchanges may accept credit card payments, wire transfers or other forms of payment in exchange for digital currencies or cryptocurrencies. As of 2018, cryptocurrency and digital exchange regulations in many developed jurisdictions remains unclear as regulators are still considering how to deal with these types of businesses in existence but have not been tested for validity.
Monero is a secure, private and untraceable currency. This open-source cryptocurrency was launched in April 2014 and soon spiked great interest among the cryptography community and enthusiasts. The development of this cryptocurrency is completely donation-based and community-driven. Monero has been launched with a strong focus on decentralization and scalability, and it enables complete privacy by using a special technique called “ring signatures.” With this technique, there appears a group of cryptographic signatures including at least one real participant, but since they all appear valid, the real one cannot be isolated. Because of exceptional security mechanisms like this, monero has developed something of an unsavory reputation; it has been linked to criminal operations around the world. Nonetheless, whether it is used for good or ill, there’s no denying that monero has introduced important technological advances to the cryptocurrency space. As of February 9, 2019, Monero had a market cap of $808.50 million and a per token value of $48.18.

A pump and dump is when an organised group of people, sometimes 200 or even 1000 strangers, arrange to buy a specific coin at exactly the same time. This drives the price of the coin up, and when their desired profit is reached, they sell and the price falls again. The coin isn’t advertised in advance, only the time at which it will be. Sounds great, but in a zero sum market anyone making a profit equals someone making a loss.

Das Unternehmen Onecoin OneLife vertrieb angebliche Schulungspakete; der Onecoin wurde als zweitstärkste Kryptowährung neben dem Bitcoin positioniert. Allein: Es existierte wohl weder die digitale Währung noch eine Blockchain, über welche die Crypto Trading  Transaktionen hätten abgewickelt werden können. Hintermänner wurden der bulgarischen Mafia zugeordnet, und der One coin in Österreich dem Sektenpräventionsindex hinzugefügt. (Mehr hierzu unter Wallstreet Online.)


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.
