I think it was in 2017 that Bitcoin hit $3000, so I will assume that you are one of the few who discovered the coin early. From your post, it seems that you made some good profit from trading which shows that you have trading skills. I know that crypto trading is highly risky but it seems you are successful and I would have loved to hear about how you traded and made so many gains that are making you boastful. You didn't tell us your fortieth birthday gift and the post didn't contain anything about short-term trading. But I wish you all the best as you enter a very important phase of your life. At this level, you should have a family and a key Investment that will be able to sustain your family.
