Don't install unknown softwares or apps on your phone or computer. I will share one of my experience on how i got cheated by one scam software. I have installed one software for earning free cryptocoins. i didn't opened the software,but still it was running in background(Later I have seen this from Task Manager) . So i have copied one of wallet address for transferring coins from one wallet to other. While pasting I have not concentrated on the copied wallet address, the scam software pasted its wallet address in place of mine. Unfortunately I lost all my hard earned money through free faucets. I checked several times and not even one time my wallet address copied. finally i uninstalled the software and came to know that all the shit happening because of that scam software. So guys! be aware of such scam apps and softwares
