Disadvantages of Cryptocurrency
1. Difficult to understand Cryptocurrencies are relatively new and come with a learning curve. People end up investing without proper knowledge and lose money to something they did not learn about.
2. Lack of knowledge People are not aware of how to use cryptocurrency and hence open themselves to hacker. The technology is somewhat complex and therefore one needs to be mindful of it before investing.
3. Not accepted widely Not many websites and companies accept digital currencies yet. Very few countries have legalized the use of cryptocurrencies. It makes it impractical for everyday use. Due to lack of acceptance, before buying or investing online or offline, you need to make sure that its accepted at that place where you want to use it. Although it is slowly getting the acceptance around the world, it will take time to take the idea entirely out of the shadows.
4. Can lose your wallet There is a possibility of losing your wallet. If you have stored the money in the form of digital currency on your phone or computer, you better remember your password and not lose those devices. Losing your coins means you wont be able to retrieve it, even with the help of legal assistance so that is just one of Bitcoins flaws.
5. No way to reverse the payment If you mistakenly pay someone by using cryptocurrency, then there is no way to get a refund of the amount paid. All you can do is to ask the person for a refund and if your request is turned down, then just forget about the money.
6. Uncertainty Since cryptocurrencies are so new, they are also very volatile. This is one of the main reasons mass adoption is taking longer than it should. Many corporations dont want to deal with a form of money that is going to go through huge swings in volatility.
I find these difficulties a big hindrance to getting involved in crypto. That's why I believe in this ICO bc they are aiming to make crypto easier to enter for all with their novice friendly UI and the first ever arbitrage exchange that will allow for less market volatility which keeps so many inexperienced and afraid people on the sidelines. Arbitrage will provide a better way to profit in this economy.
