Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain.[29] Blockchains solve the double-spending problem without the need of a trusted authority or central server, assuming no 51% attack (that has worked against several cryptocurrencies).

Take the money on your bank account: What is it more than entries in a database that can only be changed under specific conditions? You can even take physical coins and notes: What are they else than limited entries in a public physical database that can only be changed if you match the condition than you physically own the coins and notes? Money is all about a verified entry in some kind of database of accounts, balances, and transactions.
Bitcoin Cash and Bitcoin Forks: Bitcoin Cash is a spin-off of bitcoin, meant to have faster transactions, voted on and implemented by the Bitcoin community. Bitcoin Cash was probably the most successful Bitcoin fork in history, but there are always new forks popping up. Maybe Bitcoin Gold, Bitcoin Diamond, Bitcoin SV, or another will catch on.. although history says this is a rare occurrence. Keep your eye on the forks, but don’t expect them to be guaranteed the staying power of Bitcoin. Bitcoin forks are interesting altcoins, but it’s unlikely either will ever truly challenge Bitcoin for the top spot. The concept here is that Bitcoin is so relevant that it is important to keep an eye on its forks, especially the one that has really weathered the storm so far, Bitcoin Cash.

Die Erzeugung von Coins dient allerdings keinem Selbstzweck, denn gleichzeitig werden verschlüsselte Finanztransfers direkt zwischen digitalen Konten abgewickelt. Wichtig hierbei: Es gibt keine zentrale Institution wie beispielsweise eine Bank. Vielmehr führt jeder der beteiligten Rechner ein digitales „Kontobuch“, in welchem jede Transaktion genau aufgeführt wird.
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.
Risk Disclosure: Trading in financial instruments and/or cryptocurrencies involves high risks including the risk of losing some, or all, of your investment amount, and may not be suitable for all investors. Prices of cryptocurrencies are extremely volatile and may be affected by external factors such as financial, regulatory or political events. Trading on margin increases the financial risks.
If a coin isn’t in the top 50 – 100 on CoinMarketCap.com, it is not a safe and sound investment for someone who wants to see a return as a rule of thumb. Once in a while I invest in coins in the 100 – 200 by market cap range, but this is after research and is very case specific. Further down the list we go, the less demand essentially. We want to be in coins that have enough demand to sell them later (hopefully at a profit)!
Darknet markets present challenges in regard to legality. Bitcoins and other forms of cryptocurrency used in dark markets are not clearly or legally classified in almost all parts of the world. In the U.S., bitcoins are labelled as "virtual assets". This type of ambiguous classification puts pressure on law enforcement agencies around the world to adapt to the shifting drug trade of dark markets.[76]
Ethereum is more than just a currency – it’s like one giant computer housing many computers around the globe. Ethereum can respond to sophisticated requests. Its ability to store revolutionary computer programs gives Ethereum an edge on Bitcoin and has attracted attention from banks around the world. This, among other factors, has led to a jump of almost 1000% this year!

A cryptocurrency exchange is not part of the regular stock exchange. Below we will suggest using an exchange/broker Coinbase, but you can also use the related Coinbase Pro (the pro version of Coinbase with lower fees) once you sign up for a Coinbase account. Neither of these is the same as Wall Street and its exchanges (same general mechanics, different specifics, and different entities).


Litecoin was one of the first cryptocurrencies after Bitcoin and tagged as the silver to the digital gold bitcoin. Faster than bitcoin, with a larger amount of token and a new mining algorithm, Litecoin was a real innovation, perfectly tailored to be the smaller brother of bitcoin. “It facilitated the emerge of several other cryptocurrencies which used its codebase but made it, even more, lighter“. Examples are Dogecoin or Feathercoin.
Thank you for this guide. Hopefully there are no stupid questions here – but a quick clarification would be helpful. This and some of your other guides make reference to “requesting a transaction” at the very beginning of the process. What does that mean? Is is simply the request to purchase bitcoin in exchange for USD or whatever medium of exchange? Thank you in advance!

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.
