I experience a roller coaster ride like feeling at first. A lot of trial and error has been done. Instead of gaining I loose a lot because of uncontrollable emotion when it’s getting dip. I buy high and sell low in fear of loosing. 
Because of lack of knowledge and self learning process during those time.Until I realized that I always do the same mistake. I own 3 bitcoin at that time two years ago. at ¥80,000 buy price if only I’ve waited and had a knowledge back then.I profit a lot at this time.😂😂😂
