You should have avoided this matter only since he is uncle towards you so you could not get into an argument with him. Since you are a bitcoin investor you must have some plan for your investment and you would have stuck to your plan when your uncle forbade you to invest you would have just agreed to him but you would have continued your investment so you would not have lost your relationship with your uncle.
If you are still planning to get into Bitcoin, don't post anything about it in family group chat or on your WhatsApp status, this was my biggest mistake.
Be sure to maintain your privacy at all times. Investment is a very personal matter, it is better not to share these personal matters in public places because many people will not take your investment in a good light, they will try to harm you, so you should not share your investment with anyone.
