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.
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.
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.  
Instead, block producers generate blocks and are rewarded in EOS tokens based on their production rates. EOS includes a complex system of rules to govern this process, with the idea being that the network will ultimately be more democratic and decentralized than those of other cryptocurrencies. As of October 5, 2018, EOS had a market cap of $2.49 billion and a per token value of $2.74.
Nicht wenige digitale Währungen belohnen dies mit einer Art Gehalt welches für die Dienste und geleisteten Arbeitsmengen in Form der Währung selbst bezahlt werden. Das Konzept dieses Netzwerkgedanken ist also nur durch das Internet möglich. Es bietet die entsprechende Infrastruktur. So ist die technische Basis für spätere Kryptowährungen Kurse geschaffen. Es ist also sinnvoll, sich mit den teils komplexen Vorgängen dieser Branche auseinanderzusetzen.
Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes[77] and economic bubbles,[78] such as housing market bubbles.[79] Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were "nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it", and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999).[80]

Purchasing and mining cryptocurrency has evolved rapidly in recent years, and many options have captured worldwide attention. Users like the idea of cutting out third parties, such as governments and banks, and instead dealing with peers directly. For example, if a bank or company such as PayPal decided for some reason that your account had been misused, in an instant, your assets could be frozen without consulting you.

In 1983, the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash.[7][8] Later, in 1995, he implemented it through Digicash,[9] an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or any third party.
