In the end, I felt it was more likely I would mess it up if I had to do cold storage than that something terrible would happen to it online, lol (not a crazy thought, honestly - I'm so computer illiterate I could really screw it up.)
I have a bit more confidence now but seriously don't even really understand the concept.
How does it work? Is this something that I can do relatively quickly and easily without much cost?
Thanks!
