That's what I love about the bitcoin craze. So many new people new to investing, and of course they're all going to make the same beginner's mistake, use false logic. It's like 2000 all over again, when the prices of tech stocks stopped going up. Forums full of people trying to verbally muscle others because everyone had a 100% sure belief about what the future would bring.
What you say is universally recognised as naive and false, all the books/courses etc. about investing warn against thinking like that. Combined with "sell quickly if you make a profit, keep holding if you have a loss until it goes back to break even" is a good reason most beginners lose their shirt in the stock market.
