No, that is no joke.
That is a tool that may make Your $$$ equipment useless when corretly used. Test me.
Look, I am not even going to attempt to recreate what you are doing or saying, so I will not say it does or does not work. That is not what I was saying nor said.
I am asking you, in what way does this help with anything? How will it help solve a puzzle / challenge? How does it help if I lost my WIF / private key?
How does it help, in any way?
How will it replace any equipment??
