forgive my lack of knowledge because before I have never lost the key in all the wallet that I have so it's natural if I ask that and maybe I'll forget the lost wallet,, thank you
No need to apologize;) I was surprised that a member present here for several years still asks this kind of question. We learn every day, however!
I hope you have not lost much, or even that you will find your key somewhere

It could be that some forum posters here in Bitcointalk don't venture out much into the other subsections of the forum. Many only know the ann threads of the coins they are holding. I'm guilty of that in the early months but I come to understand all about distributed ledgers in due time.
