Curious what fundamentals CCs bring to the table over traditional fiat, digital or physical. Because the downsides look brutal: difficult to understand, fragile, non-reversible (sometimes a pro but often a con), expensive to operate, volatile, incompatible with KYC (sometimes a pro but often a con), etc
If you want an example, for why censorship resistance is useful, you can look back at 2011, when donations were stopped, to wikileaks, even though they were not charged with any crimes.
Crypto donations worked for them though. Bring up whatever thing that you want, about the problems, but at the end of the day, crypto donations worked for them, and visa didn't.
It is useful, to be able to make transactions to other people, in situations where banks, or credit card processors, attempt to block the transactions (even though no one has been charged with any crimes!)
