Correct, but you only have to trust a centralized company within your own country. You don't have to trust a bank or money transmitter in a foreign country. In the case of people in countries where they don't have an adequate level of government protection over financial transactions, I think it becomes more interesting. In cases like those, it's possible they don't even value their own local currency as a store of value and might feel a cryptocurrency has better odds of being worth more than zero by the time they need to spend it.
