Hi, Troy...

You can certainly copy and paste, although (if you just do that in the conventional way) you may not get all the formatting.

However, @ausbitbank has created a very neat tool that will give you the original source code of your posts, even if they are older than a week. Here's a link to the tool: https://steemviz.com/viewsource

You need to copy and paste your post address (minus everything up to the @ at the beginning of @enjoywithtroy) into the address field, and it will give you the original source code. Very cool, thanks @ausbitbank!

If you are ever going to own a large amount of bitcoins (i.e. any amount that you don't want to lose) you should very certainly consider "cold storage." I'll be happy to try and answer any questions you may have. ;)
