Bitcoin is the cryptocurrency everyone is talking about. Maybe you are new to cryptocurrencies? Do you already own Bitcoins yourself? Actually, it doesn’t matter. We will keep beginners as well as professionals covered in this guide.

Learn everything you need to know about Bitcoin. In this article, we will cover frequently asked questions. Furthermore, we dig deep into the future of cryptocurrencies. Finally, we will teach you about Bitcoin mining. At the very end, we evaluate the Bitcoin price of today and its future value predictions. So let’s start our Bitcoin guide for you.


What is Bitcoin is by far one of the most popular questions these days. To understand what a Bitcoin is, we first need to look back in time and its origin. The ledger of the Bitcoin Blockchain was distributed on January 3rd, 2009, by a person with the nickname Satoshi Nakamoto. The initial release took place 11 years ago, it was January 9th, 2009. Bitcoin was the world’s very first cryptocurrency. Then followed by so-called Altcoins, such as Dash, Ethereum, Litecoin, Ripple, and uncounted other coins.

Bitcoin is a form of digital currency. Within its Blockchain, secure data is sent through a peer-2-peer network. This data is treated as real money. Compared to regular FIAT currencies, such as USD or EUR, there is no assigned value behind the Bitcoin. Furthermore, Bitcoin is not a physical element. There is no hard coin nor any paper. The verification, as well as the value of Bitcoins, is provided by all network participants.

What are the Advantages of Bitcoin?

The major advantage of Bitcoins is, that you can store and receive crypto assets in no time. Send it to everyone you like, without the need for an intermediary. Meaning, you don’t need a bank, nor a bank account. Spending and receiving this crypto money requires a lot of computer power. Some users in the network have specialized in mining cryptocurrencies. These users are called miners and get rewarded for proving each transaction. You’ll find more information about Bitcoin Mining below. First, let us explain how Bitcoin works.


So how do Bitcoins work in real life? Another important question to answer. If you want to understand how Bitcoin works, then we need to dive deeper into the technology behind it. It’s called Block-Chain. Don’t worry! We’ve already explained this new technology in a previous post here: What is Blockchain?

Now let’s explain how Bitcoins work. So each Bitcoin (BTC) or a Satoshi (the smallest unit and equivalent to 0.00000001 BTC with eight decimals) is basically a computer file. It is stored in a digital wallet. Your wallet can be a piece of software on your computer or an App on your smartphone. Even better and safer is a hardware wallet. Don’t worry! We’ll explain to you later how bitcoin hardware wallets work.

Once you’ve received your first Satoshi or even a Bitcoin, you can start spending Bitcoins as well. Every single transaction is recorded. It’s encrypted, safe, and absolutely amazing because it’s simple.

Can Bitcoin be traced?

Absolutely! Bitcoin can be tracked and traced. Within the network, your transaction is stored in a public distributed ledger. All thanks to miners all around the world-wide-web. Therefore, it’s possible to trace the history of Bitcoins. Furthermore, the so-called proof-of-work process stops fraud completely. You are not able to make a copy of your Bitcoin and undoing a transaction is impossible.


Bitcoin Mining Hardware Farm

Bitcoin mining is the process to verify a transaction within the Block-Chain. Miners use special software and huge computing power to solve math. Blockchain technology uses cryptographic coding. Once a distributed ledger is issued it will be checked and verified by a miner. It’s a simple but smart way of issuing cryptocurrency. Furthermore, Bitcoin mining is rewarded. Miners get an incentive for each transaction they can approve.

Sure, Bitcoin has some downsides as well. Next to high investment costs, enormously high power consumption, each transaction takes about 10 minutes. These are a few reasons why developers started to create new cryptocurrencies, such as Litecoin in 2011 with a block time of under 3 minutes or the latest and fastest cryptocurrency on the market, called EOS with 2800 transactions per second.

What’s the Best Bitcoin Mining Hardware?

As mentioned before, Bitcoin Mining is very resource-intensive. The number of blocks found by miners remains steady. Each block get a proof-of-work. This is how we consider a transaction as valid. Furthermore, the verification continues by nodes. Each time a node receives a block it gets a verification right away. It all works as open-source software. This service is based on record-keeping. The bitcoin blockchain is consistent and unalterable. Bitcoin mining allows nodes to reach a secure and resistant consensus.

If you want to start Bitcoin mining yourself, here are 3 hardware options you can invest to:

Since the release of Bitcoin, we have a circulating supply of over 17 million bitcoins. The maximum supply is set to 21 million. Now you know what Bitcoin Mining is. Next, let’s talk about how to store and use your Bitcoins in a safe and legal way.


Before you can get bitcoins you need a Bitcoin wallet or let’s say digital wallet. Modern Bitcoin wallets let you store multiple cryptocurrencies in the same place. There are dozens of Cryptocurrency wallets available. Basically, the big difference between the different crypto wallets available is their operating system. Of course, there are Mobile Apps, Desktop, and even Cloud Applications. Most important is, that you make the right decision regarding features and your own criteria of your personal needs.

Bitcoin, like any other cryptocurrency, can be exchanged or used to buy products and services. The ticker symbol is BTC. All you need to start using bitcoin is a digital wallet. Ok, now you know how it works and how powerful cryptocurrencies are.

Which Bitcoin App is the Best?

The best Bitcoin App in 2020 is Coinbase. It’s a great app for consumers. They even offer enterprise solutions. Easy e-commerce integration, custody, and even ventures. The only downside of Coinbase is their high pricing and fees. Therefore our recommendation for a great Bitcoin App is PrimeXBT. Maybe the most popular Bitcoin App today.

What we really like about Blockfolio, their service is completely free. If you’re an absolute beginner, then Etoro is the one to chose. Also, Coinmama has many fans, same as CEX.io. A must mention when it comes to the best Bitcoin Apps is Bitmap. The Bitmap App lets you find the closest Bitcoin ATM near you.

When you choose to use a Bitcoin app, then always remember the safety issues we’re facing.

The best and safest Bitcoin Wallet as of today is the Trezor Model T. It is a full-featured hardware wallet. Sure, there are plenty of good Bitcoin Wallets out there. From our perspective, the following 3 cryptocurrency hardware wallets are great choices:
