Even without quantum computing threat, I do not like to hold my coins on a single wallet. I have at least 3 different bitcoin wallets because I think it is better than having just only one.
It is not. Three averagely secured wallets is worse than one with maximum security.
Maybe you will come and teach me.
How did you know that my wallets are not secure? Stop quoting someone like me unnecessarily because your post is not at all useful for me. You did not even talk about how to maximize security but you just want to post. I can as well say that someone can have a single wallet and which is not secure.
I don't need to know anything about you, learn how to think about subjects instead of responding to emotion. You said you think it is better than having just only one. What you wrote is categorically false. I showed an example where it is false. Move one and shitpost somewhere else.
