Cryptocurrency people are so funny. Recently someone with deep pockets spent six-figures embedding 9MB of encrypted data into the BTC blockchain.
I read a write-up about it one some website dedicated to cryptocurrency, and the author was especially impressed with the fact that encrypted data cannot be decrypted without a key. He noted that "not even ChatGPT could decrypt it".
Of course Cryptocurrency people don't understand cryptography... That's why they buy pretend internet money.
