I am a former test & measurement doctor engineer (geodetic metrology). I was interested in quantum metrology for a while. I live mostly in Sweden with my loving wife. I have also managed an old and broad private family Portfolio successfully -- now officially retired but still active -- and trade personally a medium-size portfolio for over 40 years. “Logic will get you from A to B. Imagination will take you everywhere.” Einstein. Note: I am not a financial advisor. All articles are my honest opinion. It is your responsibility to conduct your own due diligence before investing or trading.
