What are some examples of cryptocurrency failures?
In the ever-evolving landscape of cryptocurrency, failures are unfortunately not uncommon. Could you elaborate on some notable examples of such failures? I'm particularly interested in cases where prominent cryptocurrencies have suffered significant losses, either due to technological issues, security breaches, regulatory pressures, or other reasons. Additionally, how did these failures impact investors and the general perception of cryptocurrencies in the long term? Insights into such occurrences could help provide a better understanding of the risks associated with this volatile market.
