You are playing checkers while others are playing chess. The NOK / fiat point went over your head. Future business school students will study the slow demise of bitcoin as a non-glittering example of the 21st century's 'greater fool theory'.

How much are you down? Because it's a hard lesson, but some times you just have to cut your losses, admit defeat and walk away. And hopefully learn a lesson.
