As Bitcoin’s price hit the record $5,000 for the second time in 2017, there is probably no current investment opportunity more hyped up than cryptocurrencies and Blockchain technology. The general public and governing authorities are increasingly more aware of its advantages, and most concerns surrounding it are being refuted. A lot of companies have already invested in the technology, and it is very telling that the worldwide technology giant IBM is now considering investing “employee time and energy” into the space.

Professional services network Deloitte recently surveyed 1,000 companies across seven countries about integrating blockchain into their business operations. Their survey found that 34% already had a blockchain system in production today, while another 41% expected to deploy a blockchain application within the next 12 months. In addition, nearly 40% of the surveyed companies reported they would invest $5 million or more in blockchain in the coming year. Here are some of the most popular applications of blockchain being explored today.
Ponzi Scams: Ponzi scams, or high-yield investment programs, hook you with higher interest than the prevailing market rate (e.g. 1-2% interest per day) while redirecting your money to the thief’s wallet. They also tend to duck and emerge under different names in order to protect themselves. Keep away from companies that give you Bitcoin addresses for incoming payments rather than the common payment processors such as BitPay or Coinbase.
Truth be told, blockchain has been around for almost a decade thanks to bitcoin, but it's only now beginning to garner a lot of attention. Most businesses that are testing blockchain technology are doing so in a very limited capacity (i.e., demos or small-scale projects). No one is entirely certain if blockchain can handle being scaled as so many of its developers have suggested.
Derivatives are used in stock exchanges and are concerned with the values of assets. Smart contracts in the trading of stocks and shares could revolutionize current practices by streamlining, automating and reducing the costs of derivatives trading across the industry. Settlements could be completed in seconds rather than the three days that are needed at present. Using smart contracts, peer-to-peer trading will become a usual operation, resulting in a complete revolution in stock trading. Barclays and several other companies has already trialed a way of trading derivatives using smart contracts, but they came to the conclusion that the technology won’t work unless banks collaborate to implement it.

Transactions placed through a central authority can take up to a few days to settle. If you attempt to deposit a check on Friday evening, for example, you may not actually see funds in your account until Monday morning. Whereas financial institutions operate during business hours, five days a week, blockchain is working 24 hours a day, seven days a week. Transactions can be completed in about ten minutes and can be considered secure after just a few hours. This is particularly useful for cross-border trades, which usually take much longer because of time-zone issues and the fact that all parties must confirm payment processing.


Some people would say that trading is a form of gambling. While there these two things have something in common, there are also fundamental differences. When you gamble (and assuming that it's a fair game) you have a certain probability of winning and losing. When you trade assets, this gets much more complex. I don't want to go into too much detail here. I just want to outline the concept how you can earn Bitcoins with trading.

It seems as if overnight, the media industry has gotten the blockchain bug. Today, there are events, panels, articles and conversations about how blockchain will save journalism and advertising and marketing. In fact, Adweek has one of its very own. But before we decide whether or not this technology will be media’s savior, we wanted to answer some pretty basic questions. We’re also introducing a weekly blockchain newsletter, which you can sign up for here.
Mining is a record-keeping service done through the use of computer processing power.[e] Miners keep the blockchain consistent, complete, and unalterable by repeatedly grouping newly broadcast transactions into a block, which is then broadcast to the network and verified by recipient nodes.[67] Each block contains a SHA-256 cryptographic hash of the previous block,[67] thus linking it to the previous block and giving the blockchain its name.[3]:ch. 7[67]
To be accepted by the rest of the network, a new block must contain a proof-of-work (PoW).[67] The system used is based on Adam Back's 1997 anti-spam scheme, Hashcash.[5][83] The PoW requires miners to find a number called a nonce, such that when the block content is hashed along with the nonce, the result is numerically smaller than the network's difficulty target.[3]:ch. 8 This proof is easy for any node in the network to verify, but extremely time-consuming to generate, as for a secure cryptographic hash, miners must try many different nonce values (usually the sequence of tested values is the ascending natural numbers: 0, 1, 2, 3, ...[3]:ch. 8) before meeting the difficulty target.
Some of the more well-known micro earnings sites are Bitcoin faucets – sites which you repeatedly visit every few minutes in order to claim a very small amount of coins. Faucets are actually a subcategory of PTC websites, PTC meaning “Pay to Click”. PTC websites will usually have you click on an ad or on a button on the site in order to make money from ad sales. In return you’ll get a small amount of coins.
Before you buy Bitcoin, you need to download a Bitcoin wallet by going to a site like Blockchain.info, or to a mobile app such as Bitcoin Wallet for Android or Blockchain Bitcoin Wallet for iOS, and filling out an online form with basic details. This shouldn't take more than two minutes. (Related reading, see: Basics For Buying And Investing In Bitcoin)
Getting your monthly paycheck in Bitcoins is probably the steadiest way to earn Bitcoins. There aren't many organizations who would pay you in Bitcoins but there are some at least. And maybe there will be more as acceptance increases continuously. Gavin Andresen, core Bitcoin developer of the Bitcoin Foundation stated in this interview that he gets paid in Bitcoins. And chances are, that when your employer accepts Bitcoins they might be willing to pay you in Bitcoin, too.

If you want to give arbitrage a try, you need to get Bitcoins almost instantly. One of the few sites where you don't need to sign up is bit4coin. If you spot an opportunity and want to act on it immediately, this is a way to get a hold of Bitcoins fast. If you manage to earn Bitcoins from arbitrage, this can be very profitable after all. But start cautiously as it really does require some experience.

In the context of security, both transparency of the system and immutability of the data stored on blockchain comes into play. Immutability in computer science refers to something that cannot be changed. Once data has been written to a blockchain, it becomes virtually immutable. This doesn’t mean that the data cannot be changed – it just means that it would require extreme computational effort and collaboration to change it and then also, it would be very difficult to cloak it.
If you have been following banking, investing, or cryptocurrency over the last ten years, you may be familiar with “blockchain,” the record-keeping technology behind bitcoin. And there’s a good chance that it only makes so much sense. In trying to learn more about blockchain, you've probably encountered a definition like this: “blockchain is a distributed, decentralized, public ledger." The good news is, blockchain is actually easier to understand than that definition sounds.
In a traditional environment, trusted third parties act as intermediaries for financial transactions. If you have ever sent money overseas, it will pass through an intermediary (usually a bank). It will usually not be instantaneous (taking up to 3 days) and the intermediary will take a commission for doing this either in the form of exchange rate conversion or other charges.
However, trading Bitcoin successfully is not a matter of luck or guesswork. Profitable traders spend a substantial amount of time learning how to trade and how to overcome the many risks involved with trading. Successful traders know they might lose money in the short term but they look at it as an investment in their education, since they are aiming for the long term.
In Bitcoin, it’s like every organic food store has someone out front, offering free samples. Also, there’s a library everywhere you look, but only a few of those libraries have any good information. The largest traders would benefit a great deal if everyone just jumped blindly into Bitcoin, investing large chunks of their life savings in the process. That would be just fine by them, but it’s unlikely to happen. More likely, people are going to get involved with Bitcoin either by necessity, by chance or because someone was willing to give them a few bitcoins to get started with.
To sum it up, Bitcoin lending is a good way to make more Bitcoins from what you already have. And please notice this disclaimer: only lend through sites that you trust. Such sites will comply with the usual requirements that you expect from non-Bitcoin related sites as well. That means they have proper terms and conditions in place, they disclose their status of incorporation and contact details. Some sites in the Bitcoin world do not do this and in the end people wonder what happened to their Bitcoins. Therefore, when you earn Bitcoins from Bitcoin lending watch who you deal with and only use Bitcoins which you can afford to lose.
Think of it like the early days of the internet. The world of blockchain technology is still the wild, Wild West. By early June 2018, the total value of initial coin offerings had already outpaced the previous year. And while the past year has seen a record number of ICOs, some have been legitimate, but others are sketchier. In July 2018, for example, two Nevada men settled a lawsuit by the Securities and Exchange Commission over illegally profiting from an ICO after they made about $1.4 million in 10 days by selling shares of a company called UBI Blockchain Internet.

Do not keep too many bitcoins in any one wallet at once. Part of the reason bitcoin wallets are referred to as wallets is because it's important to think of your bitcoins as cash. Just as you wouldn't go shopping with thousands of dollars in your wallet, it is probably unwise to store large amounts of bitcoins in your wallet. Keep some bitcoins on your mobile, online, or desktop wallet but store other amounts in a more secure environment.[10]
The main reason we even have this cryptocurrency and blockchain revolution is as a result of the perceived shortcomings of the traditional banking system. What shortcomings, you ask? For example, when transferring money to overseas markets, a payment could be delayed for days while a bank verifies it. Many would argue that financial institutions shouldn't tie up cross-border payments and funds for such an extensive amount of time.
It goes further. Ebooks could be fitted with blockchain code. Instead of Amazon taking a cut, and the credit card company earning money on the sale, the books would circulate in encoded form and a successful blockchain transaction would transfer money to the author and unlock the book. Transfer ALL the money to the author, not just meager royalties. You could do this on a book review website like Goodreads, or on your own website. The marketplace Amazon is then unnecessary. Successful iterations could even include reviews and other third-party information about the book.
In 2014, prices started at $770 and fell to $314 for the year.[32] In February 2014 the Mt. Gox exchange, the largest bitcoin exchange at the time, said that 850,000 bitcoins had been stolen from its customers, amounting to almost $500 million. Bitcoin's price fell by almost half, from $867 to $439 (a 49% drop). Prices remained low until late 2016.[citation needed]
