It's still the same saying: high risks are born in FOMO markets. Opportunities are always nurtured in moments of panic. Worrying about a crash is less important than worrying whether you'll still have chips in hand if there's a sudden surge. If you believe in the industry, what's the point of not selling during a peak but selling during a crash? I can't be sure what the industry will look like in ten years, but I'm absolutely certain that I'll still be in the industry ten years from now— unless I end up working on a sewing machine.
