What part of the two explanations, you do not understand?
Or simply, you want to do FUD?

I do not see any reasonable question.
Leave the fear aside, you will have after the fork, the double of coins you have now.
I never went through the hardfork and do not understand how this happens, so I'm worried. How do I get the same number of different coins on two different wallets? What do I need to do for that?
