...if someone who gives life advice has never uttered the word "Bitcoin", you can disregard their opinion. They don't need to be a maximalist, or a bull, but they need to at least be aware of Bitcoin. If they aren't aware of it, or they're not the least bit opinionated about it, they're sleeping. Do not take opinions from someone who is asleep.
Financial blogger? Political pundit? Life coach? Ctrl+F "bitcoin". No hits? Ignore them.
(Obviously applies only to living people, and not to people whose expertise is extremely insulated from the financial world - recipe bloggers, etc.)
