Free Cloud Mining : How to protect yourself from scammers and choose the best providers




Free Cloud Mining : How to protect yourself from scammers and choose the best providers


Is free cloud mining still possible ? What are the dangers and risks involved ? Find out how to select a decent free cloud mining service and protect your funds and data
The opportunity to get crypto for free is too enticing to ignore, so the number of users on free cloud mining websites is steadily growing. Register, set up the account and gather coins — it's that simple. However, as they say, there's no such thing as a free lunch. Free coins may come at the price of your security. Let's find out what the hidden pitfalls of free cloud mining, and how to protect yourself against threats.
Before we plunge into the guidelines, let's refresh our knowledge of cloud mining.

What is free cloud mining?

In traditional mining, crypto hunters have to buy and install their own mining rigs. They consist of various expensive hardware including GPUs (graphic processing units), motherboard, fans, power units, and other stuff. Expensive hardware isn't the biggest nightmare for miners: enormous electricity bills add to the cost of mining, making it rather a luxury for deep-pocketed crypto enthusiasts. Don't forget that the mining equipment should be installed somewhere, and it emits a lot of noise and heat. 

Bad news: if the hardware isn't strong enough, these expenses will never be covered. Good news: this entire headache can be avoided if you prefer the best cloud mining service instead.

In this case, you lease mining facilities from a provider and enjoy profits without applying any effort. Aside from the package cost, users also pay a small server maintenance fee. If you do prefer free cloud mining, prepare to be charged a withdrawal fee.

With all these points in mind, you may think that cloud mining definitely makes more sense. But don't rush to make conclusions: not all cloud mining services are created equal, especially when it comes to free solutions.

Main threats of free cryptocurrency cloud mining


Remember that weak mining hardware doesn't make any substantial profit? Well, it applies to weak cloud mining, too. Why would anyone give you a lion's share of computing power for free? Here's the trick: free cloud mining renders a minor amount of computing resources at your disposal. The amount is so small that it's enough to mine some unknown coins with minimal mining complexity. Don't even try free BTC cloud mining — it’s a bad idea.

We all know that many cloud mining website's appear to be a scam : Users' funds get lost or frozen without retrieval. Who said that free mining websites will give you any guarantees? They can take coins as easily as you got them. In the best case, you would lose only time and hopes. 
In the worst case, the "free trial" will be over before you realize it. A website can charge fees you didn't know about. Thrilled by the opportunity of easy money, users don't read the fine print, or ignore user agreement at all. That's a big mistake.
Among other risks, we mention malware. There are a myriad of programs that can contaminate your browser and PC. Some initiate mining in your browser, others change the address of a wallet when a user copies and pastes it. Free websites are a hotbed of potentially harmful software that's what you should keep in mind when visiting one.

The best cloud mining safety practices

Now only paid or free mining is a risky venture by itself — there’s the whole range of threats for website users starting from trojans and finishing by some very disruptive malware. Therefore, before you buy hashing power, take care of protection.
Add 2-step authentication to your strong password. There’s no need to mention that a complicated account password is a must, right? Even trusted free cloud mining sites can be an object of brute attacks. What ensures a rock-solid protection of user’s account is two-factor authentication. You can download AUTHY app or try Google’s solution to log in using SMS codes.
Do NOT click on bright ads and banners — they can take you to phishing sites.
Use a VPN to establish safe connection. When it comes to free Bitcoin cloud mining, no one knows which dangers are hiding on the website; some viruses can infect your browser or PC. With a virtual private network, such risks are reduced considerably.

Make sure that you work with trusted cloud mining sites only: read reviews of real users and pay utmost attention to the user agreement.

Best cloud mining 2018

The main factor of success is a correctly chosen Bitcoin cloud mining service. While you wouldn’t have problems with choosing the best cloud mining 2017 solution (the majority of websites worked like clock), recently things have changed, and many well-established cloud mining companies appeared to be a scam. Let’s observe a few worthy solutions for paid and free cloud Bitcoin mining.

Genesis Mining: The best cloud mining for professionals



This is one of the most popular and reliable services out there. If you want to get the most popular coins, you should definitely try this cloud mining: Bitcoin, Ethereum, and Litecoin are supported. Genesis Mining can boast advanced data centers, a great diversity of coins available, and an intuitive interface.
This is the best cloud mining in terms of flexibility because users can distribute the hash power as they want. For instance, they can relocate 60% to Bitcoin mining and 40% to Litecoin mining. The website also offers a live feed of some of data centers.
As for the price, Genesis charges $0.14 per TH/s per day for mining Bitcoin. The price for other cryptocurrencies can vary. Although Genesis doesn’t allow for Bitcoin cloud mining free, this is a good option for starters as they can pay daily and quit as soon as it pleases them.

Eobot: best cryptocurrency cloud mining in terms of cost



Maybe Eobot is not the most convenient solution around (it doesn’t like adblockers), the range of cryptocurrencies and packages compensates for it. You can find a 24-hour contract, or a 10-year agreement — the choice is impressive. There’s a free estimator that allows calculating daily profits and figure out needed hashpower.
Maintenance fees start from $0.00021/GH/s/day, and there’s a clear explanation of how the maintenance fees works. That makes Eobot more reliable than many competitors around. Please, note that the website doesn’t support direct deposits and wire transfer — a contract can be bought with BTC or with a USD credit card via Epay.

Hashing 24


Not ready to pay right away? You can try websites that provide Bitcoin cloud mining free trial: although it won’t bring you much profit, you can check out how the service works and, probably, order a paid contract. Hashing 24 provides such an option.

This website appeared on the Net in 2016 and now it partners with BitFury to lease hashpower to clients. With its demo mode, you can simulate a BTC mining contract and find out how much you can earn with it. Besides, it’s a great training opportunity for beginners who want to understand the basics of cloud mining.
After registering, you can only sign up a lifetime contract with Hashing 24 (it can be sold anytime). If those are sold out, try the auction feature to buy hashpower from existing customers. No matter which contract you choose charges a flat fee of $0.00033 per GH/s per day. There’s also a one-time fee for buying hashpower from some particular host.

Cloud mining Bitcoin: free solutions

Today, this list wouldn’t be as huge as the best free cloud mining 2018 options, but some choice still left. Check out these websites:

Hashcoin
Bitmine
Minerport
Profit-coin
FlyingBTC
Golden-tea
Mixmine

You don’t have to make a deposit to start using those services. There are over 35 similar websites in the Net, and they can bring you a few bucks a month. That’s not much, but still fair.

Conclusion :

If you want to mine cryptocurrency for free, prepare to do your homework: there’s an enormous amount of services, but most of them appear to be a scam. When the best websites are chosen, read the Bitcoin cloud mining reviews for each of them. Real feedback is the main indicator of the website’s trustworthiness. As soon as you sign up and choose a package, don’t forget to keep the connection safe from malware, or free mining will come at the cost of spoilt hardware and compromised data.

Blockchain - Blockchain Technology



BLOCKCHAIN – BLOCKCHAIN TECHNOLOGY





A blockchain – originally block chain – is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block contains typically a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. Functionally, a blockchain can serve as “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.” 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 and a collusion of the network majority.

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. This makes blockchains potentially suitable for the recording of events, medical records, and other records management activities, such as identity management, transaction processing, documenting provenance, or food traceability.



The first distributed blockchain was conceptualised by Satoshi Nakamoto in 2008 and implemented the following year as a core component of the digital currency bitcoin, where it serves as the public ledger for all transactions. The invention of the blockchain for bitcoin made it the first digital currency to solve the double spending problem, without the use of a trusted authority or central server. The bitcoin design has been the inspiration for other applications.
A blockchain facilitates secure online transactions A blockchain is a decentralized and distributed digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the collusion of the network. This allows the participants to verify and audit transactions inexpensively. They are authenticated by mass collaboration powered by collective self-interests. The result is a robust workflow where participants’ uncertainty regarding data security is marginal. The use of a blockchain removes the characteristic of infinite reproducibility from a digital asset. It confirms that each unit of value was transferred only once, solving the long-standing problem of double spending. Blockchains have been described as a value-exchange protocol. This blockchain-based exchange of value can be completed more quickly, more safely and more cheaply than with traditional systems. A blockchain can assign title rights because it provides a record that compels offer and acceptance

 

A blockchain database consists of two kinds of records: transactions and blocks. Blocks hold batches of valid transactions that are hashed and encoded into a Merkle tree. Each block includes the hash of the prior block in the blockchain, linking the two. Variants of this format were used previously, for example in Git. The format is not by itself sufficient to qualify as a blockchain. The linked blocks form a chain. This iterative process confirms the integrity of the previous block, all the way back to the original genesis block. Some blockchains create a new block as frequently as every five seconds. As blockchains age they are said to grow in height.


Sometimes separate a blocks can be produced concurrently, creating a temporary fork. In addition to a secure hash based history, any blockchain has a specified algorithm for scoring different versions of the history so that one with a higher value can be selected over others. Blocks not selected for inclusion in the chain are called orphan blocks. Peers supporting the database don’t have exactly the same version of the history at all times. Instead, they keep the highest scoring version of the database that they currently know of. Whenever a peer receives a higher scoring version (usually the old version with a single new block added) they extend or overwrite their own database and retransmit the improvement to their peers. There is never an absolute guarantee that any particular entry will remain in the best version of the history forever. 


Because blockchains are typically built to add the score of new blocks onto old blocks and because there are incentives to work only on extending with new blocks rather than overwriting old blocks, the probability of an entry becoming superseded goes down exponentially as more blocks are built on top of it, eventually becoming very low. For example, in a blockchain using the proof-of-work system, the chain with the most cumulative proof-of-work is always considered the valid one by the network. There are a number of methods that can be used to demonstrate a sufficient level of computation. Within a blockchain the computation is carried out redundantly rather than in the traditional segregated and parallel manner.

Setting up a Bitcoin Wallet



SETTING UP A BITCOIN WALLET



The upcoming action in order to mine bitcoins is to establish a Bitcoin wallet or make use of your existing Bitcoin wallet to the Bitcoins you mine. Copay is a fantastic Bitcoin wallet and operate on various os. Bitcoin devices wallets are also attainable.
Bitcoins are actually sent out to your Bitcoin wallet using a distinct address which exclusively belongs to you. One of the most crucial steps in establishing your Bitcoin wallet is protecting it from prospective risks by allowing two-factor authentication or even trying to keep it on an offline computer system which does not possess access to the Web. Wallets may be acquired by downloading and install a software application client to your pc.

Bitcoin Mining Pool



BITCOIN MINING POOL


As soon as you’re prepared to mine bitcoins we encourage signing up with a Bitcoin mining pool. Bitcoin mining pools are teams of Bitcoin miners collaborating in order to resolve a block and share in its awards. Without having a Bitcoin mining pool, one could mine bitcoins for more than a year and never ever gain any bitcoins. It’s much more practical to share the effort and divided the reward along with a much bigger group of people . Below are a few alternatives:


When it comes to a completely decentralized pool, we strongly suggest p2pool.

The up coming pools are thought to be presently completely verifying blocks using Bitcoin Core 0.9.5 or later (0.10.2 or later suggested because of DoS weakness):

* BitMinter.
* CK Pool.
* Eligius.
* Slush Pool.

Bitcoin Mining Software


DOWNLOAD AND INSTALL COST-FREE BITCOIN MINING SOFTWARE PROGRAM


As soon as you’ve acquired your bitcoin mining equipment, you’ll need to download and install a unique program used for Bitcoin mining. There certainly are numerous softwares available that could be utilized for Bitcoin mining, however the 2 most well-known are CGminer and BFGminer that are actually command line softwares.

In case you favour the simplicity of use that arrives with a GUI, you may wish to try EasyMiner that is a click and go windows/Linux/Android system.
The work the miners should do is delivered by the softwarem it is also receives work that was already done from the bitcoin miners and use the results back to the blockchain.

How To Start Bitcoin Mining



HOW TO START BITCOIN MINING

        
To kick off mining bitcoins, you’ll have to attain bitcoin mining, hardware (or use cloud mining services– we will talk about it later). In the initial times of bitcoin, that was actually practical to mine using your PC CPU or high speed video card. These days that’s no longer feasible. Custom Bitcoin ASIC chips provide efficiency as much as 100x the ability of more outdated systems have come to dominate the Bitcoin mining market.

Bitcoin mining using just about anything less will certainly take in much more in electrical power than you are likely to gain. It’s necessary to mine bitcoins having the finest bitcoin mining hardware developed particularly for that goal. A number of firms like Avalon provide outstanding systems built especially for bitcoin mining.
Acquiring Bitcoins – In many cases, you might have to buy mining equipment using bitcoins. These days, people can easily buy the majority of equipment on Amazon.com. People also might wish to inspect the bitcoin charts.

Bitcoin Mining Guide



Bitcoin Mining Guide


Bitcoin mining is challenging business, however if you make a decent effort bitcoin mining may be an amazing opportunity to make serious money.

How Bitcoin Mining Works

Well before you begin mining Bitcoins, this is actually helpful to recognize what Bitcoin mining actually means. Bitcoin mining is achieved by calculating for the bitcoin network an operation (called “SHA256 double round hash verification procedures”), that is used to verify Bitcoin transactions as well as supply the essential safety and security for the public ledger of the Bitcoin net. The rate at which one can mine Bitcoins is calculated in hashes per second.


The Bitcoin net pays Bitcoin miners for their work by producing bitcoin to people that provide the needed computational energy. This arrives in the form of both freshly released bitcoins as well as from the transaction expenses included in the transactions verified whenever mining bitcoins. The more processing energy you provide, the more significant your portion of the reward.
