How much do you trust your macOS and all other software you've installed on it? Do you trust it with €35,000? If not, you should NOT enter your private key and go for a solution that includes offline signing.
As long as you haven't peeled the coin, you can take as long as you need to research how to do this.
Indeed I don't think that I will trust my macOS for this kind of amount. Is this so risky ?
You talk about a solution that includes offline signing. Do you have an explanation or a link for that ?
I have searched a little bit on internet and it seems a quite complicated process. Is it the process where you need to use 2 computers (one online and one offline).
Do you have more info on that ?
Many thanks already.
PS : Sorry for my stupid questions but I'm completely newbie with that universe and in addition to that English is not my mother tongue and not always easy to understand all the specific vocabulary.
