Although investing in cryptocurrencies has become a trend, the vulnerabilities in cryptocurrency have begun surfacing too. This has raised a question in everyone’s mind – Is it too early to invest in cryptocurrencies?
Bitcoin turned ten on October 31st, 2018. The cryptocurrency has made headlines on multiple occasions that brought forth its unpredictable nature. Yet, the rise of Bitcoin has inspired the creation of thousands of other cryptocurrencies. While every tech enthusiast and investor is interested in cryptocurrencies, they also continue to have mixed opinions about them. Amid the cryptocurrency scam epidemic, while David Yermack, the chairman of New York University’s Stern School of Business, said that cryptocurrencies are going to replace national currencies, Elon Musk has criticized the vulnerabilities in cryptocurrency and their poor security protocols. So who is to be believed?
Vulnerabilities in cryptocurrency
The price of Bitcoin suddenly rose to almost $20,000 and then dropped to $6,000. Due to such incidents, it is complicated for the investors to trust the ecosystem. Additionally, numerous people have no knowledge of how cryptocurrencies work, even if they own some. Thus, predicting the rise and fall in the value of cryptocurrencies is immensely complicated. Another risk of owning cryptocurrencies is that various new crypto-based companies can create their own currency only to create hype and to attract investors. But, after the investment, the price of the cryptocurrency drops, making the investor bear losses. Likewise, thousands of cryptocurrencies are made with the sole intention of scamming investors and eventually the currency dies. Hence, it becomes tricky for investors to invest in cryptocurrencies.
Scalability is one of the most debated topics when it comes to the vulnerabilities in cryptocurrency. At present, the infrastructure for cryptocurrencies is not quite mature. It is essential to understand the concept of scalability trilemma, to find the roots of the scalability problem.
The scalability trilemma states that cryptocurrencies can choose only two options between speed, decentralization, and security. The most popular cryptocurrencies, such as the Bitcoin and Ethereum, have selected decentralization and security. Hence, the speed of cryptocurrency transactions is painfully slow. When compared to giants like VISA, which can do 24,000 transactions per second, Bitcoin miners can only go for 3 to 7 transactions per second. Therefore, the slow transaction speed is highly responsible for blocking the mainstream adoption of cryptocurrencies.
Absence of regulations
Another major issue is that cryptocurrencies are not regulated at all, which makes it even harder for new investors to trust the system. In fact, a lot of people find the idea of investing in cryptocurrencies exciting, only because of the lack of any stringent regulation. We need some regulation to ensure that cryptocurrencies are used ethically and to observe stability in the cryptocurrency market. Strong regulations would only make crypto coins and tokens universally acceptable.
While some countries are making regulations for safer and efficient use of cryptocurrencies, others have absolutely banned cryptocurrencies, whereas the remaining countries have no interest at all. Regulation would reduce the vulnerability in cryptocurrency and facilitate the growth of blockchain in mainstream applications.
Currently, every cryptocurrency in the market is illiquid. Hence, selling any assets without affecting the value of the currency is almost impossible for the investors. Investors can lose hundreds of dollars before they sell the currency.
Contrary to popular belief, cryptocurrencies are prone to cybersecurity breaches and hacks. For example, the Swiss blockchain company, Trade.io, has recently reported that crypto tokens worth almost $8 million have been stolen from their cold wallet. Similarly, multiple ICOs have faced issues with security breaches and hacking, which cost the investors hundreds of millions of dollars.
Another glaring issue in this regard comes from ransomware. Hackers are attacking various firms by encrypting their data and demanding a ransom in Bitcoin worth hundreds or thousands of dollars to decrypt the compromised data. In June 2017, Nayana, a South Korean web hosting organization had to pay around $1 million to decrypt the data of almost 3400 customers stored in 150 servers.
Although the ecosystem for cryptocurrencies is in its early stages, the existing obstacles can be tackled with practical solutions. To create a secure ecosystem, cryptocurrency owners should address the risks of cryptocurrencies. For starters, a global regulatory framework can be an excellent option to govern the application of cryptocurrencies. A union of multiple countries can come together to form a regulation model that is feasible for every economy. Another alternative is forming a self-governance model with the help of identity reputation. A self-governing model will help the ecosystem guide itself by regulating transactions based on the previous transactions of organizations and individuals. Better regulation can also solve the liquidation problem with cryptocurrencies.
Popular crypto coins are already working on their scalability. Bitcoin is developing a Bitcoin Lightning Network, where every investor has a dedicated node that is connected to at least one other node. The network aims to create a multi-signature wallet that correctly knows the owner of the currency and the receiver of the bitcoin. Such measures will effectively reduce the transaction costs and make the transactions faster. Similarly, Ethereum is planning to apply the process of blockchain sharding. The entire network is partitioned into sections called shards, and every shard will hold their own state and transaction history. With sharding, each node would process transactions for certain shards, instead of having a single network do all the work. This process will increase the rate at which transactions are processed collectively by the shards, assisting in speeding up the transactions. Likewise, other coins and tokens can adopt similar methods to address the scalability and vulnerability issues with cryptocurrency.
For overcoming the issue of volatility, the rise and fall in the value of cryptocurrencies need to be controlled. It is essential to understand that various factors affect the demand for crypto coins and tokens. Hence, a cryptocurrency project named Basis plans to maintain the value of cryptocurrencies by increasing and decreasing the supply of the currency, just like central banks. Similar options can be applied by other cryptocurrencies to address the volatility problem. Likewise, appropriate measures can be taken to tackle the other vulnerabilities in cryptocurrency, such as those related to cybersecurity. Hiring better security divisions with skilled cybersecurity professionals, who can implement a secure authentication mechanism and adopt web application security controls, should be the highest priority. Security officials need to conduct security training, and audit hardware and software regularly. Moreover, investors should avoid using cloud storage and storing private keys offline.
Implementation of cryptocurrencies
Even though there are concerns regarding the vulnerabilities in cryptocurrency, they can be adopted by organizations from various industries and sectors. Big players have realized that the benefits of cryptocurrencies outweigh the limitations, given the fact that the underlying technology is only getting more advanced. Hence, industry giants such as Virgin Galactic and Microsoft have already deployed cryptocurrencies in their organization.
By following their footsteps, cautious adoption of blockchain and cryptocurrencies will help any organization attain a competitive edge in the market. But, for successful deployment of blockchain and cryptocurrencies, business leaders, such as the CTOs and the CIOs, need to be thoroughly informed about every aspect of cryptocurrency. Moreover, finding out which problems can be fixed with cryptocurrencies is significant for strategizing its effective deployment. Hiring a team with niche skills can vastly improve the process of adoption and ensure better security standards. Before the implementation of cryptocurrencies, it is essential to guide the employees and explain how cryptocurrencies are going to affect the organization and the work culture.
With further developments in blockchain technology, the vulnerabilities in cryptocurrency will eventually be taken care of. And, as finance and tech experts have pointed out, cryptocurrencies have the potential to revolutionize finance, healthcare, technology, and various other market segments.
