Bitcoin prices had roared back by mid-2024. As a result of this vast range of volatility, many people consider cryptocurrencies a speculative bubble.

Whether or not cryptocurrency is a security is a bit of a gray area right now. To back up a little, generally, a “security” in finance is anything that represents a value and can be traded.
