Disadvantages of Cryptocurrency
A crypto is a digital or virtual kind of currency, marked by cryptography, a network that’s distributed across an oversized number of computers which makes it nearly impossible to counterfeit or double-spend. Basically, it is a system that allows for online secure payments, which are denominated in virtual tokens.
1. Illegal transactions:
Since the privacy and security of cryptocurrency transactions are high, it’s hard for the government to trace down any user by their wallet address or keep tabs on their data. Bitcoin has been used as a mode of payment (exchanging money) during many illegal deals in the past, like buying drugs on the dark web. It has also been used by some people to convert their illicitly acquired money to hide its source, through a clean intermediary.
2. Risk of Data Loss:
The developers wanted to make virtually untraceable ASCII documents, strong hacking defenses, and impenetrable authentication protocols. It would make it safer to position money in cryptocurrencies than physical cash or bank vaults. But if any user loses the private key to their wallet, there is no getting it back. The wallet will remain locked away along with the number of coins inside it. It might result in the loss of the user.
3. Power lies in few hands:
Although cryptocurrencies are known for their feature of being decentralized, the flow and amount of some currencies within the market are still controlled by their creators and some organizations. These holders can manipulate the coin for enormous swings in its price. Even hugely traded coins are at risk of these manipulations like Bitcoin, whose value doubled several times in 2017.
4. Buying NFTs with other tokens:
Some cryptocurrencies can only be traded in one or some fiat currencies. It forces the user to convert these currencies into one all told the most currencies, like Bitcoin or Ethereum first and then through other exchanges, to their desired currency. It can apply to just some cryptocurrencies. By doing this, the extra transaction fees are added within the method, costing unnecessary money.
5. No refund or cancellation:
If there is a dispute between concerned parties, or if someone mistakenly sends funds to a wrong wallet address, the coin cannot be retrieved by the sender. It might be utilized by many folks to cheat others out of their money. Since there are no refunds, one can easily be created for a transaction whose product or services they never received.
6. High consumption of Energy:
Mining cryptocurrencies require plenty of computational power and electricity input, making it highly energy-intensive. The main culprit during this is often Bitcoin. Mining Bitcoin requires advanced computers and plenty of energy. One cannot do it on ordinary computers. Major Bitcoin miners are in countries like China that use coal to produce electricity. It has increased China’s carbon footprint tremendously.
7. Vulnerable to hacks:
Although cryptocurrencies are very secure, exchanges don’t seem to be that secure. Most exchanges store the wallet data of users to figure their user ID correctly. This data is often stolen by hackers, giving them access to lots of accounts.
After getting access, these hackers can efficiently transfer funds from those accounts. Some exchanges, like Bitfinex or Mt Gox, have been hacked within the past years, and Bitcoin has been stolen in thousands and countless US dollars. Most exchanges are highly secure nowadays, but there is always a possibility for a further hack.
