Edit:
Also on an unrelated note.....was thinking....you hear about malware , viruses etc....infecting computers and searching for any addy in an attempt to sweep away your precious crypto. So I fig why not place a small Satoshi sample say 1000 Sats on your PC by leaving an exposed non encrypted paper wallet key so in the event it's swept away it would kind of give you an indication something is going on on your PC. And yeah it could still be infected and not swept too...but what the hell...giving it a try as well.
Yes I have a safe PC...run malware and antivirus programs and only safe websites are loaded...but I figure why not run a kind of litmus test for potential unknown attacks if they ever happen
