You're not wrong, but not all crypto is the same. Some have switched to "proof of stake" which removes all the energy wasted on mining, some allow to write programs into it that can execute automatically to do some interesting things, and some allow sending fractions (thousandths, millionths) of a USD with barely a transaction fee.
Even in Europe, free bank-to-bank transfers take a couple days to execute (there is a paid option for instant transfers), and have a minimum of 0.01€ which might or might not be what you want to tip/pay someone for their content.
