So you can use it to conduct illegal cross border money transfers... of course most cryptos aren't anonymous and even those are you still need to transfer it to a local currency etc. for that functionality to be useful.
Getting payment is crypto is excellent if you live in a third world country like me. And a lot of services are enabling crypto payments so illegal stuff isn’t really all of it. One example is grab app which is huge in asian market. Getting payment and transferring to local currency takes about 20 mins included manual clicks for me. Comparing this to bank system which takes a week and has at least 30x cost, it is obviously a huge improvement.
