Cryptocurrency mining is a favourite of fraudsters. Get a fake or stolen credit card number / identity, sign up for an account on a cloud provider, and spin up instances to do your mining. Depending on how quickly the provider reacts to the pattern of behaviour, or identifies the account as fraudulent etc, you can have earned a reasonable pay-off. If the provider isn't paying attention and/or doesn't have good fraud detection in place, it may be a few months before your account and resources are terminated (assuming the payments eventually bounce, and the provider gives you a chance to fix it)
