Analysts claim that cryptocurrencies have been in a speculative bubble for many years. It means that the price of a specific coin or any digital assets, in general, is far greater than their "actual" value.
Many critics believe that the actual value of cryptocurrencies is absolute zero. Concerns about a potential crypto bubble peaked in 2018 when the market value of cryptocurrencies skyrocketed. Accusations of a crypto bubble are frequently inspired by the idea that cryptocurrency's main function is sheer speculation.
