LoyceV,

Thank you again!
You are a great teacher for newbies, really!

Yes!

Question
about importing private key.
You wrote that there were a risk to loose btc using this option because of:
1. Because of malware/spyware. OK, I understand this.
2. Because of myself.  If I mess up something.

Could you please tell,
How can btc be lost if I mess up something when:
- To import private key one must do a basic 10 seconds operation: Copy private key in old wallet and paste it to new wallet.
- As long as old wallet is not deleted, and old private key is not deleted, nothing can be lost  even if I do importing private key completely wrong.

This is how I understand the situation now!
If it is not correct, please tell me what I understood wrong.
So that I know where to be especially careful!

Many, many thanks for your help and your patience with such a "student" like me :-)
