Even Elon musk may likely choose the 10btc over a breakfast/dinner with himself, lol. It is against etiquette to even talk while eating, so definitely there's nothing beneficial that can be discussed over the very little words that will be said on the table. Unless a relationship can be developed in such a time and Elon somehow will become friends that our relationship can expose me to opportunities better than the value of 10btc, then yes i'd choose the time with Elon, otherwise it is the 10btc straight up.
