Sending money to people internationally without the blessing, permission or fees of your government or central bank is the primary utility. It is simply astounding to me that otherwise intelligent people can't understand this simple and incredibly useful function.

If I want to send $10 to my cousin in Brazil or Madagascar, how do I do that exactly without crypto? Sending him $10 in litecoin takes a few minutes to process through the blockchain, and costs just a few cents in processing fees. What is the alternative, especially if he doesn't a bank account or ready access to a bank? Paying high fees to Moneygram or Western Union, waiting an extended period of time and undergoing an onerous KYC process that often ends up in your funds being returned or rejected from many foreign countries?

If you are wealthy, live in the United States, have a bank account, no interest in privacy, and are looking to send and/or receive money from other wealthy people from the United States who also have bank accounts and don't have any interest in privacy, then crypto holds no allure.
