Bitcoin is a decentralized digital currency. There is no physical existence of Bitcoin, just the verification and value it has been given by a global peer-to-peer network. All these transactions are recorded in Blockchains.
The blockchain is very much like a public shared ledger. All the confirmed transactions performed ever using Bitcoins are recorded in this ledger. These blocks are an ultra-secure data, treated like cash. All the transactions are received and sent through wallets which are digitally signed. To ensure security, bitcoin wallets come with a private key or seed. These signatures ensure that the transaction is performed by the current owner of the wallet and provides with the mathematical proof. In reality, there is no transfer of Bitcoins but the change of ownership and quantities of Bitcoins.
If person A needs to transfer Bitcoins to person B, the transaction carries three parts.
To send the Bitcoins to anybody you require two things.
A bitcoin address is generated by an individual randomly. It mainly consists of a sequence of numbers and letters.
A private is a secret key with a unique sequence of numbers and letters.
When person A wants to send coins to person B, she signs a message with her private key to authorize the transaction. The transaction will include,
Person A then sends the number of Bitcoins to the Bitcoin network from her wallet. Once entered in the network, miners will then verify the transaction included in the blockchain. The miners will then solve the mathematical puzzle and in the end, it will verify that person B is the new owner of the specified number of coins.
Just like account ledgers containing amount and names, blockchains function almost the same. People exchange money by changing this file.
For instance, if person A sells a product to person B for $5, person A’s balance goes up by $5 and person B will have a reduced balance of $5.
There are no third parties involved in the system, like banks or other financial institutions. So, who takes control and responsibility of controlling and maintain this ledger? Every coin holder maintains their own copy of the ledger. All the participants can see each other’s ledger and their balances. In Bitcoin ledgers, these names are exchanged with specific numbers to ensure anonymity.
To keep every ledger synced and harmonized, there is a protocol that needs to be followed. To do a transaction you tell everyone by broadcasting a message with your account number, the receiver’s account number and the amount to be transferred. Every coin holder around in the world will update their ledger.
There are people who help in maintaining the system. You can simply use the system to perform the transaction without maintaining the ledger.
To ensure sender is the real owner of the account, Bitcoin requires a signature to verify it, but a mathematical signature.
When an account is created, a private key is generated mathematically linked to that account number. The private key and the text from the transaction are processed through a special cryptographic function to generate a signature. To make sure the signature is done by the wallet owner and to the specific transaction, another function allows the other people to verify the signature. These signatures cannot be copied as they are unique to each transaction.
The main problem with the system is that this cannot verify when a transaction was performed.
For example, if a person falsely has to withdraw 2 cheques out of an account but it has enough money to cover one account. the bank will refuse the second cheque due to an inadequate amount of cash after the with drawl of the first cheque. It is much harder to determine the order in Bitcoin. Due to the scattered individuals all over the world taking part in the transaction, there may be a delay in different orders in different places. Fraudsters could lie about these time lapses.
Two recipients might both think their transaction is first and ship a product allowing the fraudster two spent the money twice.
New transactions go into a pool of pending transactions. These transactions then get into the giant chain that locks in their order. A lottery is then held, enabling participants to choose a transaction of their choice to solve a special problem to link them to the end of the chain. The person to find the solution first wins and gets their transaction next in the chain.
That’s how pretty much all the transactions in the Bitcoin system are performed.
The value of the cryptocurrencies is fluctuating every moment. That is why investors still consider these cryptocurrencies are very new with supreme returns.
Ethereum’s value was all-time high over $400 in June but fell lower $200 for the first time since May 30. Furthermore, Bitcoin’s price correction wiped off closely $4billion in its market price.
Bobby Lee, CEO of the Bitcoin exchange told CNBC that the true value has yet to be discovered. He states in a Hong Kong conference, “If you think about it, the volatility is natural for an asset class that is so new. There’s no price discovery for it (yet).”
He explains that people need to discover the true value of the digital currency bitcoin. They have a tendency to trade these assets at a firm, promotional level before market analysis it could be worth more and this a time when the price jumps.
After getting legalized in several countries, the currencies have seen a significant rise in the popularity. Such as Japan legalized the bitcoins as a payment method.
Managing director of Hong Kong-based commodities and digital currency trading house Dave Chapman says, “We now sort of at … a tipping point, where people are now considering bitcoin or ethereum or digital assets as more mainstream.” And,” A lot of the people that we service are actually very comfortable with having 1 percent of their net worth into bitcoin as it is considered to be the best way to invest in bitcoin.”
He also adds, “There’s no other asset class in the world that could’ve given you the historic performance of this sector … the historic performance, which is obviously not representative of future earnings, … does appeal to a lot of people.”
The analyst has made mixed estimations about these digital asset’s values and market cap as well. According to the BTCC’s Lee experience, the market cap for the Bitcoin will hit at least $trillion by 2025. He says, “I think it’s going to go to at least $1 trillion, if not maybe $10 trillion in the next five to ten years.”
Bitcoin’s current market cap is about $38.55 billion on supply and around 16 million in circulation. Whereas, the total supply of the bitcoin is 21 million. According to Lee, “In a grand of scheme of things, it’s nothing. Many, many companies are worth way more than that.” Furthermore, tech companies already have their market cap in billions or trillions of dollars.
Regulations may help to increase the credibility of these digital assets. Accordingly, Japan, Russia, and China are introducing new regulations.
In the end, Chapman also added that a number of investors have a fear of loss. That’s why they are still not ready for bitcoin investment in the digital currency market.
“We get a lot of people who are like ‘You know what? I still don’t believe in this experiment. I’m not really a believer, but I’m tired of sitting on the sidelines and missing out.”
This post is going to be a detailed review on the best Android Bitcoin wallets however, I’m doing my part by warning you that mobile wallets are the least safe type of bitcoin wallets.
Read: Types of Bitcoin Wallets
The reason behind this is the fact that mobile devices can be easily stolen, lost or broken. The private keys will be stored on your device if you possess a mobile wallet. So, if your device gets destroyed, your coins can’t be accessed either. Meanwhile, if you have a backup pin created for your wallet that you have stored in a safe place, your coins can be retrieved.
Now let’s get on with the reviews!
Mycelium is a well-known mobile wallet that provides advanced privacy and security features to its users. It is an open source software program and thus is frequently updated to become a safer and faster wallet in the market. The coins can only be accessed through the mobile wallet as it does not have a web or desktop interface. One of the major benefits is that you can use Mycelium along with a hardware wallet in order to achieve maximum security of your coins.
Airbitz is another well-known open source Android Bitcoin wallet. The wallet is quite similar to BreadWallet because of its simplicity but packs a variety of features to enhance the security of your coins.
BreadWallet is known to be one of the simplest android wallets out there. It consists of very basic “send” and “receive” options which make it very easy to use. At the moment, it is only available for Android and iOS.
Jaxx is comparatively new and proves to be a strong option among the other mobile wallets. It has the ability to hold a diverse variety of cryptocurrencies, it can also allow you to access your funds from multiple devices. However, one drawback of Jaxx is that it is not an open source software program, which has raised to a lot of safety concerns recently. You are recommended not to store large sums of coins.
Copay is a multisignature wallet created by BitPay. Multisignature means that the wallet requires more than one person to approve a transaction before its confirmation. This gives it an increased amount of security if that’s your main concern. Copay has an iOS, Android, and desktop version.
GreenAddress is a solid choice for people who are well experienced with Bitcoin as it has a bit of a weak user interface. Regardless, it offers good features needed to keep your coins secure. If nothing works out then GreenAddress has got your back!
Just a reminder that not every wallet application on Google Play Store is verified. Some apps are created with the sole purpose of stealing the coins you transfer on to the mobile wallet. So, you’re advised to do your research before trusting any unknown wallet. Be sure that you are downloading the official application and not a malicious wallet.
The dark web is basically a concealed portion of the world wide web that can be accessed only using TOR or any other anonymous network such as Project Freenet. People use these mediums in order to access services, products, and content that cannot be accessible on the normal web. You can find videos, music, pictures, books and various other illegal items here. A very well-known dark web marketplace that goes by the name of Silk Road, has everything you can think of.

Now, when you use TOR it is recommended that you use a VPN and route your traffic through it. What happens is that your ISP is unable to find out if you are accessing the Dark web and even if your IP address happens to leak due to some security flaw, it is not your actual IP address but of the VPN server you are routing your connection through.
All in all, a VPN is that extra layer of security you need to avoid any feds banging on your door at 4 AM.
However, not all VPN service providers are genuine and could land you in trouble. Here are the safest options you could go for:
With NordVPN, you can be assured that your anonymity remains no matter what. It does not keep any logs so there are no chances of any data leakage or exposure online. Along with this, it has a peer-to-peer friendly VPN service and you can use up to 6 devices simultaneously. Bitcoin is accepted here and NordVPN operates from the Panama.
Besides a few glitches in the performance and variations in the speed at peak hours, there aren’t many drawbacks of this.
The headquarters of Perfect Privacy’s servers are located in New Zealand. They ensure that no logs are stored to avoid any risks in the future. Forget data breaches as Perfect Privacy is ready to put its company at stake for your privacy. Also, it doesn’t require any third-party tools, which decreases any chances of issues. It even provides you server-based-Ad and malware filters to ensure you maintain a secure browsing experience.
However, one setback is that it takes quite some time to set it up initially.
Similar to a fellow VPN service provider, Torguard also operates from the United States. But they’re known to have privacy as their main aim which means they would even consider relocating if it were ever necessary. Torguard as well does not keep any logs which is essential for safe browsing of the dark web.
Also, Torguard has an impressive amount of servers located worldwide making it a tough competitor.
ExpressVPN allows you to conduct any peer-to-peer activities while ensuring that no logs are kept. It’s also known for its fast downloading speed, which makes it so much easier to browse the dark web.
The only drawback is that you can use only two devices at a time and you have to separately log in to each device.
Don’t be alarmed that IPVanish is located in the United States as this does not make it unsafe as a VPN option. Similarly, it accepts Bitcoin as well. No logs are stored and the OpenVPNsecurity protocol along with the 256-bit AES encryption allows you to browse the web without any issues.
A drawback is that only two devices can be used simultaneously.
We’ve outlined the top 5 VPN service providers that include all the specifications for safe and secure web browsing. It is your choice to experiment with whatever that seems suitable for you as the five companies mentioned above have you covered!
Let us know in the comments section below if you try any of these out. Also, check out this list of Darknet marketplaces you can visit with the help of the above-mentioned VPN service providers.

We’re surrounded by all sorts of mysteries that are yet to be solved but, the biggest one yet is how the cryptocurrency king, Bitcoin, was created and why. Keeping that in mind, there have been various bitcoin conspiracy theories on the internet. Here are some of the ones that seem more legitimate than others.
It’s a fact that organizations such as JPMorgan don’t see much profit in bitcoin but, they’re all in for the technology that lies behind it. Mt. Gox drove bitcoin’s value to higher limits, while JP Morgan composed a price crash by selling over 8000 coins to drive the price back down.
Parallelly, JPMorgan was funding anti-bitcoin articles teamed up with mainstream media firms. To tell you the truth, all these concepts, do sound quite reasonable, however, it seems unreal to think that such an institution would intentionally crash the bitcoin price.
Has it ever occurred to you that Satoshi Nakamoto could be an artificial intelligence? Well, considering that the world has been on several hunts as to find out the persona behind the pseudonym that no one can actually think that it might be an AI created by a hidden government. While this theory does seem a little far off, it spurs up some really exciting discussions.
Many seem to believe that the Chinese created Bitcoin as to wipe out their dependence on the US dollar. While it is a fact that China has been working with Russia and others to create a payment system, it is doubtful they would create bitcoin to substitute the US Dollar.
This is a theory that has been quite popular on the web that how bitcoin was created as an experiment by the NSA. Claiming that Satoshi Nakamoto is actually a pseudonym behind the top-secret cryptocurrency project. Also, it is said that the NSA has access to the SHA-256 algorithm, which makes bitcoin a lot less secure than what it’s assumed to be.
In 2013, a conspiracy theory had risen from the Bitcointalk forums. A user came up with the concept that major governments like US and China were buying bitcoins in bulk for themselves. Let’s not forget both these governments had first opposed the cryptocurrency when it emerged, which makes this theory quite believable.
