This covered in official guide
https://github.com/Kotlin/kotlinx.coroutines/blob/master/docs/composing-suspending-functions.md#concurrent-using-async

launchrunBlockingWhich queues the coroutines on the same thread
Instead, you can consider using GlobalScope, or even better, declaring your function as an extension on CoroutineScope interface. You can also put it in a component that has its own CoroutineScope.
Or just pass a dispatcher as context to the top most launch

If all coroutines are surrended must of the time a single thread will do just fine.
