Sorry to hear about your family trouble, it's not fair how your uncle reacted and I hope you will learn from it for the future. My family is a bit different, we see each other regularly and are very close. Everybody in my family knows that I invest in crypto currencies for several years now and they don't really judge me for it. In the beginning they were worried that I would lose all my money. And after the big crypto hype they wanted me to sell all my coins. It took quite a long time to make them understand that I am in for the long run and not going to react to short-term price movements. By now they are all fine with my choices and accept them. For me it's all about being honest within the family and not getting judged by them. In case my uncle would react the same way like yours I would probably reduce the contact to a minimum.
