Initial Coin Offerings: Risk or Opportunity?


A company seeking to raise money to create a new coin, app, or service can launch an ICO as a way to raise funds. Interested investors can buy into an initial coin offering to receive a new cryptocurrency token issued by the company. This token may have some utility related to the product or service that the company is offering, or it may just represent a stake in the company or project.

When a cryptocurrency project wants to raise money through ICO, the project organizers' first step is to determine how they will structure it. ICOs can be structured in a few different ways, including:. These three different types of ICOs are illustrated below:. Alongside structuring the ICO, the crypto project usually creates a white paper , which it makes available to potential investors via a new website dedicated to the token.

The promoters of the project use their white paper to explain important information related to the ICO:. Investors can generally use fiat or digital currency to buy the new tokens, and it's increasingly common for investors to pay using other forms of crypto such as Bitcoin or Ethereum.

These newly issued tokens are similar to shares of stock sold to investors during an IPO. If the money raised in an ICO is less than the minimum amount required by the ICO's criteria, then all of the money may be returned to the project's investors. The ICO would then be deemed unsuccessful. If the funding requirements are met within the specified time period, then the money raised is spent in pursuit of the project's goals.

Anyone can launch an ICO. With very little regulation of ICOs in the U. But this lack of regulation also means that someone might do whatever it takes to make you believe they have a legitimate ICO—and then abscond with the money. Of all the possible avenues of funding, an ICO is probably one of the easiest to set up as a scam.

If you're really set on buying into a new ICO that you heard about, make sure to do your homework. The first thing is to make sure the people putting up the ICO are real and accountable. One key thing to look for is the product's leads' history with crypto or blockchain. If it seems the project doesn't involve anyone with relevant, easily verified experience, that's a red flag. Famous actors and entertainers like Steven Seagal also sometimes encourage their followers to invest in a hot new ICO.

Boxing superstar Floyd Mayweather Jr. Centra Tech was ultimately deemed a scam in court, resulting in the two celebrities settling charges with U. Even if anyone can establish and launch an ICO, that doesn't mean that everyone should. If you are thinking about organizing an initial coin offering, ask yourself if your business would substantially benefit from an ICO.

ICO activity began to decrease dramatically in , in part because of the legal gray area that ICOs inhabit. Investors can research and find ICOs in which to participate, but there is no surefire way to stay abreast of all the latest initial coin offerings. You can use websites like TopICOlist. ICOs can generate a substantial amount of hype, and there are numerous sites online where investors gather to discuss new opportunities. Investors seeking to participate in ICOs should first familiarize themselves broadly with the cryptocurrency space and become educated about any ICO before participating.

Because ICOs are barely regulated, prospective investors should exercise extreme caution when investing. In March , the U. There is no guarantee that an investor won't be on the losing end of a scam when investing in an ICO. To help avoid ICO scams, you can:. Another further consideration is that you typically need to own another cryptocurrency to invest in an ICO.

Because new tokens issued in an ICO can often only be purchased using an established cryptocurrency such as Bitcoin , ICO investors need to already have two cryptocurrency wallets :. Initial public offerings of stock raise money for companies that are becoming public and result in the distribution of shares of the company's stock to investors.

For ICOs, crypto companies raise funds through the sales of coins or tokens. In both cases, investors are bullish, whether about the company or the cryptocurrency, and invest based on some belief that the asset's value will increase over time.

The primary difference between an ICO and an initial public offering of stock is that investing in an ICO doesn't secure you an ownership stake in the crypto project or company. ICO participants are gambling that a currently worthless currency will later increase in value above its original purchase price.

This lack of regulation coupled with the often decentralized nature of crypto projects means that an ICO's structure can vary significantly. By contrast, the structure of most IPOs is largely similar. Though IPOs are funded by generally more conservative investors anticipating a financial return, ICOs may receive funding from risk-tolerant supporters who are keen to invest in a new, exciting project.

An ICO differs from a crowdfunding event because it offers the possibility of financial gain over time, whereas crowdfunding initiatives essentially just receive donations. Online services can facilitate the generation of cryptocurrency tokens, making it exceptionally easy for a company to consider launching an ICO.

ICO managers generate tokens according to the terms of the ICO, receive them, and then distribute the tokens by transferring the coins to individual investors. But because ICOs are not regulated by financial authorities like the SEC, funds that are lost due to fraud or incompetence may never be recovered.

Early investors in an ICO are usually motivated by the expectation that the tokens will gain value after the cryptocurrency launches. This is the primary benefit of an ICO: the potential for very high returns. But the legality of cryptocurrency or digital assets is not guaranteed to persist. In , the People's Bank of China officially banned ICOs, slamming them as counterproductive to economic and financial stability. The Chinese government in went on to ban cryptocurrency mining and declared all cryptocurrency transactions illegal.

The SEC's HoweyCoin is named after the agency's Howey Test , which is a test to determine whether an investment qualifies as a security. Munchee was attempting to raise money to create a cryptocurrency that would work within the app to order food.

Ethereum's ICO in is an early, prominent example of an initial coin offering. Sometimes ICOs with remarkable returns on investment are not the projects that raise the most money, and vice versa. The amounts raised by ICOs reached a peak in and and have declined in recent years. When evaluating the success of an ICO, you can consider both the amount of money raised in the ICO and the return generated on investment.

Because each individual's situation is unique, a qualified professional should always be consulted before making any financial decisions.

Understanding The DAO Attack

Smart contract technology — the implementation of electronic contracts, embodied in code and performed automatically by computers — is maturing fast. Despite ambitious projects run by start-ups, major financial institutions and others, no smart contract solutions have yet significantly displaced traditional ways of contracting, but that is bound to change. The technological and legal hurdles to implementing a fully-fledged, mature smart chain solution remain daunting. But in the longer term, it is difficult to imagine that the production, execution and performance of legal agreements will not be transformed by the trends of digitisation and automation that are reshaping so many other spheres of human activity. A smart contract is an automatable and enforceable agreement.

Initial coin offerings ICOs are one of the several by-products in the world of the cryptocurrencies. Start-ups and existing businesses are turning to alternative sources of capital as opposed to classical channels like banks or venture capitalists. The investors, of course, hope for an increase in the value of the token in the short term, provided a solid and valid business idea typically described by the ICO issuers in a white paper. However, fraudulent activities perpetrated by unscrupulous actors are frequent and it would be crucial to highlight in advance clear signs of illegal money raising. In this paper, we employ statistical approaches to detect what characteristics of ICOs are significantly related to fraudulent behavior. We leverage a number of different variables like: entrepreneurial skills, Telegram chats, and relative sentiment for each ICO, type of business, issuing country, team characteristics.

A distributed contract is a method of using Bitcoin to form agreements with people via the block chain. Contracts don't make anything possible that was previously impossible, but rather, they allow you to solve common problems in a way that minimizes trust.

Leveraging Applications of Formal Methods, Verification and Validation: Applications

IPOs usually apply to established businesses that sell partial ownership shares in their company as a way to raise funds. In contrast, ICOs are used as a fundraising mechanism that allows companies to raise funds for their project in very early stages. When ICO investors purchase tokens, they are not buying any ownership in the company. ICOs can be a viable alternative to traditional funding for tech startups. Often, new entrants struggle to secure capital without an already functional product. In the blockchain space, established firms rarely invest in projects on the merits of a white paper.

Picture this: A thief steals millions of dollars by hacking into an investment fund. What if you could just hit the undo button and get that money back? That was the dilemma that the creators of Ethereum, an upstart digital currency platform, recently faced. Founded in by a group of researchers led by Russian-Canadian Vitalik Buterin — then only 19 years old — its currency, ether, is the second-most valuable digital currency after bitcoin. In the wake of the hack, Buterin decided to turn back the clock through a software update and reset the entire system to its previous state — i. The reset created a so-called hard fork, which split Ethereum into two parallel systems.

This allows Tezos to occupy second place in the ranking of the most successful ICO deals.

Tokenization of Real Estate: What, Why and How

As a wider variety of data is fed into blockchain networks, from weather indexes to IoT sensor readings, users worldwide are continuing to discover the power of blockchain applications for use cases far beyond money and finance. In the sustainability sector, hybrid smart contracts— smart contracts that leverage blockchain infrastructure and off-chain data and computing resources—are emerging as an innovative solution for enabling global communities to more easily come together to incentivize green practices and directly verify their impact. A growing amount of environmental science research points toward the benefits of regenerative agriculture techniques for protecting natural ecosystems. Regenerative agriculture is a holistic land use practice that involves planting multipurpose tree species alongside indigenous vegetables and superfood plants to create an agro-ecology system. Regenerative agriculture focuses not only on reducing the carbon footprint and ensuring sustainability but also on going beyond traditional conservation practices to reverse the direction of climate change. For small organizations, these challenges are considerable, while large organizations tend to grapple with high administrative overhead and slow program creation and enactment.
