I Used Cracked Windows 10 Activated (download from internet) on my laptop, and installed Electrum wallet.
Not the best thing to do as everyone here is preaching that you shouldn't download any crack softwares from the internet, specially Windows.
Is my wallet safe?
is there a spy on the cracked windows?
how do know that Cracked didn't inject malware and spyware, and send the data from my laptop to their server?
Maybe you can ran AV, and detect that there is malware or spyware. However, not all AV can detect a newly design or a variant of a recent malware or spyware. So you don't know if there is one in your system until it's too late.
