Beginner’s Guide: What are Crypto Private and Public Keys?
Marius Bogdan Dinu • December 16, 2018
What is the Private Key?
The Private Key is a sophisticated form of cryptography that allows users to access their cryptocurrency. A private key is an integral aspect of Bitcoin and Altcoins, and its security make up helps to protect a user from theft and unauthorized access to funds.
What is the Public Key?
The Public key is a cryptographic code that allows users to receive cryptocurrencies into their personal wallet (account). The public key coupled with the private key are significant tools required to ensure the security of the crypto economy. It is an encryption technique that uses a paired public and private key (or asymmetric key) algorithm for secure data communication.
When dealing with cryptocurrencies, a user is usually given a public address and a private key to send and receive coins or tokens. The public address is where the funds are deposited and received. But even though a user has tokens deposited into his address, he won’t be able to withdraw them without the unique private key. The public key is created from the private key through a complicated mathematical algorithm. However, it is near impossible to reverse the process by generating a private key from a public key.
How do they work?
A private key is shared only with the key’s initiator, ensuring security. For example:
- A and B represent a message sender and message recipient, respectively. Each has its own pair of public and private keys. A, the message initiator or sender, sends a message to B. A’s message is encrypted with B’s public key, while B uses its private key to decrypt A’s received message.
- A digital signature, or digital certificate, is used to ensure that A is the original message sender.
- In order to verify this, B uses A’s public key to decrypt the digital signature, as A must previously use its private key to encrypt the digital signature or certificate. If readable, the digital signature is authenticated with a certification authority (CA).
In short, sending encrypted messages requires that the sender use the recipient’s public key and its own private key for encryption of the digital certificate. Thus, the recipient uses its own private key for message decryption, whereas the sender’s public key is used for digital certificate decryption.
The private key can take a few different forms, usually depicted as a series of alphanumeric characters, which makes it hard for a hacker to crack. Most users represent their wallet keys in wallet import format, which has 51 characters. Think of a public address as a mail box, and the private key as the key to the box. The mailman, and anyone really, can insert letters and small packages through the opening in the mailbox. However, the only person that can retrieve the contents of the mailbox is the one that has the unique key. It is therefore, important to keep the key safe because if it is stolen or gotten without authorization, the mail box can be compromised.
Closing Thoughts
Remember that if you don’t have the private keys of your crypto, you are not the real owner! There’s no perfect way to store your crypto assets , but do not ever disclose your private keys to anyone and make sure you are storing them safely! It will help you a lot throughout your Crypto Adventure!

Bitcoin has grown from a fringe technological curiosity into a major financial asset, and at the heart of its ecosystem lies one of its most powerful mechanisms: mining. But while mining was once the domain of tech-savvy enthusiasts with custom-built rigs, it has now become increasingly accessible to anyone with a smartphone. For those wondering how to mine Bitcoin or is mining bitcoin profitable in today’s world, the answer might just lie in the palm of their hands. How Bitcoin Mining Works Bitcoin mining is the process by which new bitcoins are entered into circulation and transactions are verified and added to the blockchain. Miners solve complex cryptographic puzzles to validate blocks of transactions. The first one to solve it gets rewarded with newly minted Bitcoins and transaction fees. This system ensures network security and maintains the decentralized nature of Bitcoin. In the past, mining required expensive hardware (like ASICs), constant energy consumption, and deep technical know-how. But recent innovations have given rise to mobile-friendly methods that offer alternative ways to participate in the mining ecosystem. Methods of Bitcoin Mining via Mobile Apps Cloud Mining: This method allows users to rent mining hardware hosted in remote data centers. Users lease a portion of mining power (hash rate) and earn a share of the mined Bitcoin. Many cloud mining platforms offer apps to monitor earnings. However, some cloud mining services have been criticized for a lack of transparency and reliability. Mobile Mining: These apps claim to mine Bitcoin directly from your phone by using its CPU or GPU. However, due to limited processing power, energy inefficiency, and wear on devices, mobile mining is generally inefficient and mostly unprofitable. Many apps in this category are more simulations than real mining tools. Digital Mining: A more advanced alternative, digital mining involves owning hash power tied to real-world mining hardware, without ever having to manage physical equipment. Through platforms like GoMining, users buy digital miners via mobile apps and earn daily Bitcoin rewards based on their virtual miner's hash power. This approach bridges real mining infrastructure with digital convenience. How to Choose a Bitcoin Mining App Selecting the best Bitcoin mining app requires careful research. Here are some key things to consider: Transparency: Make sure the bitcoin mining app provides clear information about how it works, what kind of rewards you can expect, and how mining is executed. Legitimacy: Check for user reviews, community feedback, and platform transparency. If an app promises sky-high returns with no effort, it might be a scam. Ease of Use: A good crypto mining app should be user-friendly, with intuitive navigation and helpful features such as dashboards, tutorials, and support. It’s a plus, if the app is easy for newcomers. Performance Tools: Features like a built-in crypto mining calculator help users estimate potential rewards based on input variables like hash power and token holdings. Cross-Platform Compatibility: Look for apps that work across multiple devices, including a Bitcoin mining app for Android and other mobile platforms. Ecosystem Support: Some apps go beyond mining, offering gamified tasks, referral bonuses, or access to early crypto project launches. What to Avoid Unrealistic Promises: If it sounds too good to be true, it probably is. Avoid apps guaranteeing huge returns in short periods. Poor Reviews or Lack of Information: A quick search should reveal whether the app is legitimate or has issues. Fake Mining Games: Many apps posing as " mining games " only simulate mining activity without any real payouts. Lack of Contact Info or Support: A legit app should have accessible customer service and a traceable company behind it. GoMining: A Hybrid Platform with Real Mining Power One of the most talked-about platforms in the digital mining space is GoMining. Designed to simplify access to real Bitcoin mining, GoMining lets users buy digital miners linked to physical mining hardware in professional data centers. Unlike typical cloud services, GoMining provides full transparency and offers real-time mining rewards, tracked directly in the app. It's not just a bitcoin mining app, it's a fully-fledged crypto mining ecosystem that includes: A user-friendly interface is available as an app for both Android and iOS, and as a desktop version.

The transformation that Bitcoin went through, from a niche digital currency to a globally recognized asset, has revolutionized how we think about money, investment, and technology. By advancing decentralized finance, Bitcoin directly challenged the existing financial institutions. With the surge in interest came a growing need for innovative approaches to access this ecosystem. That’s why Bitcoin mining , once an obscure activity reserved for early tech adopters, has quickly grown into a sophisticated, multi-tiered industry. Today, it’s even more than that. Cryptocurrencies live by their own laws and regulations; there are trends to follow, and elements to understand before getting involved. Yet, despite Bitcoin’s evolution, it continues to face challenges that require new, user-friendly solutions. The Traditional Path: From CPUs to ASICs In the early days of Bitcoin, enthusiasts mined using their personal computers’ central processing units (CPUs). The power was more than enough, and the lack of interest in a new, untested technology didn’t allow for Bitcoin to make waves. Still, as competition grew, users upgraded to more powerful graphics processing units (GPUs), which offered better efficiency. The popularity of Bitcoin also surged, and that’s when Bitcoin mining slowly stopped being just a hobby. Eventually, application-specific integrated circuits (ASICs) became the standard for serious miners, offering unparalleled speed and energy efficiency. But ASICs are expensive, consume large amounts of electricity, and demand constant maintenance. Large facilities led by companies spearheaded the change and Bitcoin mass adoption . This evolution effectively shut out the average user from participating in mining. Today, running an independent mining operation requires significant capital, technical knowledge, and physical space. There are seemingly too many barriers that deter mainstream adoption. Mining as a Service: Cloud and Mobile Solutions To bridge this gap, cloud mining platforms were created. These services allow users to rent hash power from remote data centers without dealing with hardware directly. While more accessible, cloud mining platforms often lack transparency, and many have been accused of being Ponzi schemes. Some users never see a return on their investment, and that’s just part of the issue. Companies often offer a locked contract that doesn’t allow a user any control over their mining operation. Meanwhile, mobile mining apps claim to offer Bitcoin mining on phones, using device CPUs or offering simulation-based experiences. These apps are typically inefficient, power-draining, and often function more as marketing tools than real mining mechanisms. Nonetheless, they illustrate the public demand for convenient and passive income apps tied to Bitcoin. Digital Bitcoin Mining: The Most Modern Approach Digital mining is an evolution of both cloud and mobile mining. It enables users to own digital miners. A digital miner is a virtual asset that represents actual hash power in professional mining facilities. Unlike cloud mining contracts, digital miners are ownable. As such, they can be upgraded, sold, or transferred, offering more control and transparency. Digital mining removes the need for hardware ownership, offering users real mining rewards without the hassle of dealing with the issues related to traditional mining. It represents a step forward in making legit Bitcoin mining accessible to anyone, anywhere. GoMining: A Digital Mining Ecosystem A leader in this new wave is GoMining, a crypto mining website that offers a fully digital experience. Through its app and web platform, users can purchase and manage digital miners that are directly linked to physical mining operations. GoMining combines ease-of-use with real mining infrastructure. It's a Bitcoin mining website designed for both beginners and seasoned crypto users. The core of its ecosystem may be built around accessible Bitcoin mining, but there’s so much more to the platform. What sets GoMining apart is its holistic approach: Two Mining Modes: Aside from solo mining, which allows users to acquire daily BTC rewards according to the power of their farm, there is another mode. Miner Wars is a clan-based mining game, in which players join clans and compete against each other for rewards. Launchpad: A Bitcoin-centric launchpad allows Bitcoin projects to present their tokes for pre-sale. GOMINING Token: Used to pay maintenance fees at a discount, access token presales, and participate in the ecosystem through voting. The tokens can also be invested in a liquidity pool . Secure Wallet: Integrated features that allow users to hold and store their Bitcoin rewards and GOMINING tokens. Passive Income Potential: Rewards are distributed daily, and users can optimize earnings through strategic upgrades and in-game participation. LBH (Level-Based Hashrate): A tiered system that rewards long-term engagement and miner power accumulation. The GoMining platform is available as a Bitcoin miner app , suitable for mobile devices and providing Bitcoin mining on phone without draining local resources. This makes it a strong contender among crypto mining sites aiming for mass adoption of Bitcoin. Why Digital Mining Matters Digital mining lowers the barriers to entry in the Bitcoin mining world. It provides an accessible gateway into an otherwise complex industry. For those asking whether mining is still profitable, the answer is nuanced. It can bring considerable rewards, but only when done through efficient, transparent, and legitimate platforms. GoMining’s transparency, use-case versatility, and gamified features make it one of the most promising players in the space.

One doesn’t have to be a Bitcoin Maximalist to realize that Bitcoin is the cornerstone of all crypto. Whenever the environment is good for the world’s no.1 cryptocurrency, it’s favorable for all the rest of them. But like any trend with high potential, in time, Bitcoin has become somewhat inaccessible. After its price had soared, Bitcoin quickly captured the attention of large companies, turning mining from an enthusiast-exclusive hobby into a massive business with huge mining farms working day and night. Mining Bitcoin: The Hidden Barriers to Entry What is mining Bitcoin really about? Without getting into the technicalities of it, mining is a process of minting new Bitcoin and rewarding it to users for solving complex math problems, using their hash power. Said hash power usually comes from either a powerful GPU or an even more powerful ASIC miner device. Those can be expensive, which is why average users don’t always view mining as a potential source of passive income . The initial investment, summed up with monthly payments for electricity and maintenance, makes it a high-risk operation without a guaranteed return. It doesn’t help that after each halving, rewards for the same amount of work are cut in half. While this is what keeps Bitcoin supply balanced, it renders a lot of mining equipment obsolete after only 4 years of service. In that sense, traditional mining requires more than just knowledge of the equipment and even more than being prepared to offer a hefty initial investment. It requires strategy and understanding of the trends as well as the ins and outs of the market. As a result, many users, even potentially interested in mining, had to resort to watching Bitcoin succeed from the sidelines, never having a chance to participate in its growth. There should be ways to remedy that. Mining Going Digital Digital mining is a relatively new approach based on something called Liquid Bitcoin Hashrate . Essentially, we are dealing with digital miners – virtual devices connected to real physical data centers. These devices can be upgraded, sold, and bought. The first collection of digital miners – The Greedy Machines – was released by GoMining in 2022. Digital Mining vs. Cloud Mining: What’s the Difference? While both digital mining and cloud mining aim to make Bitcoin mining more accessible, they differ significantly in structure, ownership, and long-term value. Understanding the differences between them can help users make smarter decisions when choosing how to mine. Cloud mining is a service-based model. Users rent a portion of mining power (hashrate) from a provider who owns and operates the physical equipment. In exchange, the user receives a share of the mining rewards. However, cloud mining contracts are often time-limited, opaque, and rigid. Users typically have no control over the equipment, can’t upgrade it, and are locked into contracts that may not be profitable if Bitcoin prices drop or network difficulty increases. Digital mining, introduces a more transparent and ownership-based alternative. Instead of renting power, users own a digital miner. This gives the user autonomy over their asset. Rewards are issued daily or weekly, based on the mining mode, and users can track their performance in real time via an app. One of the key differences lies in flexibility and strategy. With GoMining’s digital miners, users can reduce costs using GOMINING tokens, apply promo codes, or enhance earnings through perks like GoMiner avatars. This isn’t possible in traditional cloud mining setups, which tend to offer a fixed, “set-it-and-forget-it” approach. Ultimately, digital mining offers greater transparency, control, and earning potential. When it comes to passive income ideas , an ecosystem that empowers users to make strategic decisions and benefit from long-term participation in the mining economy is the best way to go. Understanding the GoMining Ecosystem The GoMining ecosystem is a powerful reimagining of how Bitcoin mining can work in today’s fast-paced, digital-first world. By removing the traditional barriers of entry, like expensive hardware, high electricity costs, and technical know-how, GoMining has made mining accessible to virtually anyone. Whether you’re a seasoned crypto enthusiast or a newcomer looking to generate passive income, GoMining offers a streamlined and user-friendly alternative to conventional mining operations. But GoMining is more than just a mining solution. It's a comprehensive platform that introduces multiple layers of utility, strategy, and gamification. One of its standout features is Miner Wars , a play-to-earn game where users form clans and compete for BTC and GOMINING token rewards. It blends entertainment with earnings, making mining more engaging and social. Another cornerstone of the ecosystem is the GoMining Launchpad – a crypto launchpad that provides early access to promising Bitcoin projects. This allows GOMINING token holders to diversify their holdings and invest in new crypto ventures ahead of public listings. It's an intelligent way to extend earning potential beyond traditional mining. GoMining also helps users save and optimize earnings through several integrated features. For example, paying maintenance fees with GOMINING tokens gives users up to 20% in discounts. Everything within the ecosystem is designed to work together: users mine BTC, earn and spend GOMINING tokens, use the app to manage activity, and grow their influence through the VIP and referral systems. The GOMINING token price is tied to the platform’s success, making it an integral part of the long-term value proposition. Bitcoin Mining in 2025? Today, in 2025, many newcomers to the crypto world wonder how to earn Bitcoin and what is Bitcoin Mining . The good news is, it’s not just by trading anymore. The landscape of mining has, indeed, changed. But thanks to accessible platforms, like GoMining, mining Bitcoin is once again possible without large investments or extensive tech knowledge.
