Hackers and scammers never stops inventing new strategies for stealing from people. But, how you avoid these scammers is still the same ways – stop installing apps from unknown sources, make use of the main app stores whenever you want to install an application.

Stop opening unsolicited mails, when you see mails from people you don't know, just delete it immediately. And another thing is to avoid giving out information about yourself, because when they lay hands on your information they can as well use it to do something against you. I'm always careful with how I use cryptocurrency because I know that they are not like PayPal, there is no way you can reverse your money, once it's sent, just say bye-bye to it.
